![]() - Use extent maps to track pagecache page status instead of bufferhead state. - Refactor pagecache read and write paths to use the new iomap library functions, which enable us to drop the old bufferhead code for pagesize == blocksize filesystems. - Set up parallel per-block-per-page metadata to track subpage information that was tracked by buffer heads, which enables us to drop the old bufferhead code for pagesize > blocksize filesystems. - Tie a deferred ops control structure to a transaction so that we can take advantage of an upper-level dfops without having to plumb pointer passing through the code. - Refactor the deferred ops code to track deferred ops as part of the transaction structure (instead of as a separate data structure) so that we can simplify the scoping rules around defer_ops. - Refactor twisty delwri buffer submission code to avoid deadlocks. - Shorten and fix indenting problems in the scrub code. - Detect obviously bad summary counts at mount and fix them. - Directly associate deferred ops control structure with a transaction so that callers no longer have to manage it themselves. - Remove a couple of IRIX-era inode macros. - Remove the long-deprecated 'barrier' and 'nobarrier' mount options. - Clean up the inode fork structure a bit. - Check for bad fs summary counter values in the superblock. - Reduce COW fork lookups during writeback. - Refactor the deferred ops control structures into the transaction structure, thereby eliminating the need for transaction users to handle the deferred ops as a separate data structure. - Add the ability to repair AG headers online. - Fix a crash due to insufficient return value checking. - Various fixes and cleanups. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAltwVGoACgkQ+H93GTRK tOt3bw//WaG1mR44Oo/mhf27MaEJK74LXeViqCH4Sdk10gujClTVnl6h33ChAyEi 7BT4x1JtwM6xOh7nPsXQy/besVxWadjQcTtAz/3U2wJoFyOX2+I27SAawrmX6jfR Hi1DxXFFK7z/8YvuZqYl3vTgxMNb7bLAUybe2sYX8q+vrQaUvl9eLQlHSaT3sxrc /lBkog1dYmbw3yjLnWYpQtC0I6Pa3ZuG/S2vpeJ2H5MADtzrRNjuC9MHZJW7tIGm +rCLm0agk8yFkEA84VvS5Afee3TppY/JBaYlsvG1rp3bs0fELAJFnzS4g/QDbbsX HAKPcMICJksF4C9y0Xb7wXPz/4PKur5/OSuGXN4QtOivOEoAdWfh2PLInqAjo/Le mO92PdkBucfVqJzfEC2q2QAnGIaJlG8txhAz87wZ1YfZDQQlJDy385Z9GQXfUpy5 /1xH7V0cze1ZBSxWSddSFg0gCtaWSerfp0CmAG3A+HWKIN6c/ZNSCrqdq0DBC99D qOn6ThjckZWGvz/KV5xBr/KvUYOpSeEyREtgcAN008TiUaNy4nOhWV2xgLGuPY/J ed4V2B9qVbq+l+sZyzukB8cmOXmcCey6omwJ7LqZzoTWTAtTQtM2MwhaQFUWtQG8 mCqPXJp1XyL24sn0bI1t2NuKgQcs6QEQWX3zN4DA6I+N9+sTDqo= =2G+i -----END PGP SIGNATURE----- Merge tag 'xfs-4.19-merge-6' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "This is the second part of the XFS changes for 4.19. The biggest changes are the removal of buffer heads frm XFS, a massive reworking of the deferred transaction operations handling code, the removal of the long defunct barrier/nobarrier mount options, and the addition of a few more online repair functions.
