H A D | blk-lib.c | diff 39722a2f2bcd82bdecc226711412d88b54fcb05b Mon Jul 01 18:51:19 CEST 2024 Christoph Hellwig <hch@lst.de> block: limit the Write Zeroes to manually writing zeroes fallback
Only fall back from hardware Write Zeroes failures when blkdev_issue_write_zeroes returns -EOPNOTSUPP;
Note that blkdev_issue_write_zeroes turns any failure into -EOPNOTSUPP when the write zeroes queue limit has been cleared to 0, so this still catches all I/O errors where the driver detected missing support for the hardware acceleration.
