f2fs: fix to avoid potential deadlock
Quoted from Jing Xia's report, there is a potential deadlock may happen between kworker and checkpoint as below:
[T:writeback] [T:checkpoint] - wb_writeback - blk_start_plug bio contains NodeA was plugged in writeback threads - do_writepages -- sync write inodeB, inc wb_sync_req[DATA] - f2fs_write_data_pages - f2fs_write_single_data_page -- write last dirty page - f2fs_do_write_data_page - set_page_writeback -- clear page dirty flag and PAGECACHE_TAG_DIRTY tag in radix tree - f2fs_outplace_write_data - f2fs_update_data_blkaddr - f2fs_wait_on_page_writeback -- wait NodeA to writeback here - inode_dec_dirty_pages - writeback_sb_inodes - writeback_single_inode - do_writepages - f2fs_write_data_pages -- skip writepages due to wb_sync_req[DATA] - wbc->pages_skipped += get_dirty_pages() -- PAGECACHE_TAG_DIRTY is not set but get_dirty_pages() returns one - requeue_inode -- requeue inode to wb->b_dirty queue due to non-zero.pages_skipped - blk_finish_plug
Let's try to avoid deadlock condition by forcing unplugging previous bio via blk_finish_plug(current->plug) once we'v skipped writeback in writepages() due to valid sbi->wb_sync_req[DATA/NODE].

f2fs: move f2fs to use reader-unfair rwsems
f2fs rw_semaphores work better if writers can starve readers, especially for the checkpoint thread, because writers are strictly more important than reader threads. This prevents significant priority inversion between low-priority readers that blocked while trying to acquire the read lock and a second acquisition of the write lock that might be blocking high priority work.

Pull f2fs updates from Jaegeuk Kim: "In this round, we've tried to address some performance issues in f2fs_checkpoint and direct IO flows. Also, there was a work to enhance the page cache management used for compression. Other than them, we've done typical work including sysfs, code clean-ups, tracepoint, sanity check, in addition to bug fixes on corner cases.
Enhancements: - use iomap for direct IO - try to avoid lock contention to improve f2fs_ckpt speed - avoid unnecessary memory allocation in compression flow - POSIX_FADV_DONTNEED drops the page cache containing compression pages - add some sysfs entries (gc_urgent_high_remaining, pending_discard)
Bug fixes: - try not to expose unwritten blocks to user by DIO (this was added to avoid merge conflict; another patch is coming to address other missing case) - relax minor error condition for file pinning feature used in Android OTA - fix potential deadlock case in compression flow - should not truncate any block on pinned file
In addition, we've done some code clean-ups and tracepoint/sanity check improvement"

mm: introduce memalloc_retry_wait()
Various places in the kernel - largely in filesystems - respond to a memory allocation failure by looping around and re-trying. Some of these cannot conveniently use __GFP_NOFAIL, for reasons such as:
- a GFP_ATOMIC allocation, which __GFP_NOFAIL doesn't work on - a need to check for the process being signalled between failures - the possibility that other recovery actions could be performed - the allocation is quite deep in support code, and passing down an extra flag to say if __GFP_NOFAIL is wanted would be clumsy.
Many of these currently use congestion_wait() which (in almost all cases) simply waits the given timeout - congestion isn't tracked for most devices.
It isn't clear what the best delay is for loops, but it is clear that the various filesystems shouldn't be responsible for choosing a timeout.
This patch introduces memalloc_retry_wait() with takes on that responsibility. Code that wants to retry a memory allocation can call this function passing the GFP flags that were used. It will wait however is appropriate.
For now, it only considers __GFP_NORETRY and whatever gfpflags_allow_blocking() tests. If blocking is allowed without __GFP_NORETRY, then alloc_page either made some reclaim progress, or waited for a while, before failing. So there is no need for much further waiting. memalloc_retry_wait() will wait until the current jiffie ends. If this condition is not met, then alloc_page() won't have waited much if at all. In that case memalloc_retry_wait() waits about 200ms. This is the delay that most current loops uses.
linux/sched/mm.h needs to be included in some files now, but linux/backing-dev.h does not.

This patch tries to mitigate lock contention between f2fs_write_checkpoint and f2fs_get_node_info along with nat_tree_lock.
The idea is, if checkpoint is currently running, other threads that try to grab nat_tree_lock would be better to wait for checkpoint.
