Wong" Date: Mon, 15 Apr 2024 14:54:17 -0700 Subject: xfs: create deferred log items for file mapping exchanges Now that we've created the skeleton of a log intent item to track and restart file mapping exchange operations, add the upper level logic to commit intent items and turn them into concrete work recorded in the log. This builds on the existing bmap update intent items that have been around for a while now. Signed-off-by: Darrick J.

Wong" Date: Mon, 15 Apr 2024 14:54:20 -0700 Subject: xfs: condense extended attributes after a mapping exchange operation Add a new file mapping exchange flag that enables us to perform post-exchange processing on file2 once we're done exchanging the extent mappings. If we were swapping mappings between extended attribute forks, we want to be able to convert file2's attr fork from block to inline format. (This implies that all fork contents are exchanged.) This isn't used anywhere right now, but we need to have the basic ondisk flags in place so that a future online xattr repair feature can create salvaged attrs in a temporary file and exchange the attr fork mappings when ready. If one file is in extents format and the other is inline, we will have to promote both to extents format to perform the exchange. After the exchange, we can try to condense the fixed file's attr fork back down to inline format if possible. Signed-off-by: Darrick J.

Wong" Date: Mon, 15 Apr 2024 14:54:44 -0700 Subject: xfs: use atomic extent swapping to fix user file fork data Build on the code that was recently added to the temporary repair file code so that we can atomically switch the contents of any file fork, even if the fork is in local format. The upcoming functions to repair xattrs, directories, and symlinks will need that capability. Repair can lock out access to these user files by holding IOLOCK_EXCL on these user files. Therefore, it is safe to drop the ILOCK of both the file being repaired and the tempfile being used for staging, and cancel the scrub transaction. We do this so that we can reuse the resource estimation and transaction allocation functions used by a regular file exchange operation. Signed-off-by: Darrick J.
