Fri, 19 Jan 2024 18:10:23 +0100

Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfsPull netfs updates from Christian Brauner: "This extends the netfs helper library that network filesystems can use to replace their own implementations. Both afs and 9p are ported. cifs is ready as well but the patches are way bigger and will be routed separately once this is merged. That will remove lots of code as well. The overal goal is to get high-level I/O and knowledge of the page cache and ouf of the filesystem drivers. This includes knowledge about the existence of pages and folios The pull request converts afs and 9p. This removes about 800 lines of code from afs and 300 from 9p. For 9p it is now possible to do writes in larger than a page chunks. Additionally, multipage folio support can be turned on for 9p. Separate patches exist for cifs removing another 2000+ lines. I've included detailed information in the individual pulls I took. Summary: - Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O calls to prevent these from happening at the same time. - Support for direct and unbuffered I/O. - Support for write-through caching in the page cache. - O_*SYNC and RWF_*SYNC writes use write-through rather than writing to the page cache and then flushing afterwards. - Support for write-streaming. - Support for write grouping. - Skip reads for which the server could only return zeros or EOF. - The fscache module is now part of the netfs library and the corresponding maintainer entry is updated. - Some helpers from the fscache subsystem are renamed to mark them as belonging to the netfs library. - Follow-up fixes for the netfs library. - Follow-up fixes for the 9p conversion"* tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: (50 commits) netfs: Fix wrong #ifdef hiding wait cachefiles: Fix signed/unsigned mixup netfs: Fix the loop that unmarks folios after writing to the cache netfs: Fix interaction between write-streaming and cachefiles culling netfs: Count DIO writes netfs: Mark netfs_unbuffered_write_iter_locked() static netfs: Fix proc/fs/fscache symlink to point to "netfs" not "../netfs" netfs: Rearrange netfs_io_subrequest to put request pointer first 9p: Use length of data written to the server in preference to error 9p: Do a couple of cleanups 9p: Fix initialisation of netfs_inode for 9p cachefiles: Fix __cachefiles_prepare_write() 9p: Use netfslib read/write_iter afs: Use the netfs write helpers netfs: Export the netfs_sreq tracepoint netfs: Optimise away reads above the point at which there can be no data netfs: Implement a write-through caching option netfs: Provide a launder_folio implementation netfs: Provide a writepages implementation netfs, cachefiles: Pass upper bound length to allow expansion ...

86fb59411553c553fe327db067a2435ecb72c80f - Merge tag 'netfs-lib-20231228' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs

Thu, 28 Dec 2023 11:34:22 +0100

Merge tag 'netfs-lib-20231228' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fsPull netfs updates from David Howells:The main aims of these patches are to get high-level I/O and knowledge ofthe pagecache out of the filesystem drivers as much as possible and to getrid, as much of possible, of the knowledge that pages/folios exist.Further, I would like to see ->write_begin, ->write_end and->launder_folio go away.Features that are added by these patches to that which is already there innetfslib: (1) NFS-style (and Ceph-style) locking around DIO vs buffered I/O calls to prevent these from happening at the same time. mmap'd I/O can, of necessity, happen at any time ignoring these locks. (2) Support for unbuffered I/O. The data is kept in the bounce buffer and the pagecache is not used. This can be turned on with an inode flag. (3) Support for direct I/O. This is basically unbuffered I/O with some extra restrictions and no RMW. (4) Support for using a bounce buffer in an operation. The bounce buffer may be bigger than the target data/buffer, allowing for crypto rounding. (5) ->write_begin() and ->write_end() are ignored in favour of merging all of that into one function, netfs_perform_write(), thereby avoiding the function pointer traversals. (6) Support for write-through caching in the pagecache. netfs_perform_write() adds the pages is modifies to an I/O operation as it goes and directly marks them writeback rather than dirty. When writing back from write-through, it limits the range written back. This should allow CIFS to deal with byte-range mandatory locks correctly. (7) O_*SYNC and RWF_*SYNC writes use write-through rather than writing to the pagecache and then flushing afterwards. An AIO O_*SYNC write will notify of completion when the sub-writes all complete. (8) Support for write-streaming where modifed data is held in !uptodate folios, with a private struct attached indicating the range that is valid. (9) Support for write grouping, multiplexing a pointer to a group in the folio private data with the write-streaming data. The writepages algorithm only writes stuff back that's in the nominated group. This is intended for use by Ceph to write is snaps in order.(10) Skipping reads for which we know the server could only supply zeros or EOF (for instance if we've done a local write that leaves a hole in the file and extends the local inode size).General notes: (1) The fscache module is merged into the netfslib module to avoid cyclic exported symbol usage that prevents either module from being loaded. (2) Some helpers from fscache are reassigned to netfslib by name. (3) netfslib now makes use of folio->private, which means the filesystem can't use it. (4) The filesystem provides wrappers to call the write helpers, allowing it to do pre-validation, oplock/capability fetching and the passing in of write group info. (5) I want to try flushing the data when tearing down an inode before invalidating it to try and render launder_folio unnecessary. (6) Write-through caching will generate and dispatch write subrequests as it gathers enough data to hit wsize and has whole pages that at least span that size. This needs to be a bit more flexible, allowing for a filesystem such as CIFS to have a variable wsize. (7) The filesystem driver is just given read and write calls with an iov_iter describing the data/buffer to use. Ideally, they don't see pages or folios at all. A function, extract_iter_to_sg(), is already available to decant part of an iterator into a scatterlist for crypto purposes.AFS notes: (1) I pushed a pair of patches that clean up the trace header down to the base so that they can be shared with another branch.9P notes: (1) Most of xfstests now pass - more, in fact, since upstream 9p lacks a writepages method and can't handle mmap writes. An occasional oops (and sometimes panic) happens somewhere in the pathwalk/FID handling code that is unrelated to these changes. (2) Writes should now occur in larger-than-page-sized chunks. (3) It should be possible to turn on multipage folio support in 9P now.All in all these patches remove a little over 800 lines from AFS, 300from 9P, albeit with around 3000 lines added to netfs. Hopefully, I willbe able to remove a bunch of lines from Ceph too.I've split the CIFS patches out to a separate branch, cifs-netfs, wherea further 2000+ lines are removed. I can run a certain amount ofxfstests on CIFS, though I'm running into ksmbd issues and not all thetests work correctly because of issues between fallocate and what theSMB protocol actually supports.I've also dropped the content-crypto patches out for the moment asthey're only usable by the ceph changes which I'm still working on.The patch to use PG_writeback instead of PG_fscache for writing to thecache has also been deferred, pending 9p, afs, ceph and cifs all beingconverted.* tag 'netfs-lib-20231228' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: (40 commits) 9p: Use netfslib read/write_iter afs: Use the netfs write helpers netfs: Export the netfs_sreq tracepoint netfs: Optimise away reads above the point at which there can be no data netfs: Implement a write-through caching option netfs: Provide a launder_folio implementation netfs: Provide a writepages implementation netfs, cachefiles: Pass upper bound length to allow expansion netfs: Provide netfs_file_read_iter() netfs: Allow buffered shared-writeable mmap through netfs_page_mkwrite() netfs: Implement buffered write API netfs: Implement unbuffered/DIO write support netfs: Implement unbuffered/DIO read support netfs: Allocate multipage folios in the writepath netfs: Make netfs_read_folio() handle streaming-write pages netfs: Provide func to copy data to pagecache for buffered write netfs: Dispatch write requests to process a writeback slice netfs: Prep to use folio->private for write grouping and streaming write netfs: Make the refcounting of netfs_begin_read() easier to use netfs: Make netfs_put_request() handle a NULL pointer ...Signed-off-by: Christian Brauner List of files: /linux/fs/cachefiles/Kconfig
