New code for 5.8:
- Various cleanups to remove dead code, unnecessary conditionals, asserts, etc. - Fix a linker warning caused by xfs stuffing '-g' into CFLAGS redundantly. - Tighten up our dmesg logging to ensure that everything is prefixed with 'XFS' for easier grepping. - Kill a bunch of typedefs. - Refactor the deferred ops code to reduce indirect function calls. - Increase type-safety with the deferred ops code. - Make the DAX mount options a tri-state. - Fix some error handling problems in the inode flush code and clean up other inode flush warts. - Refactor log recovery so that each log item recovery functions now live with the other log item processing code. - Fix some SPDX forms. - Fix quota counter corruption if the fs crashes after running quotacheck but before any dquots get logged. - Don't fail metadata verification on zero-entry attr leaf blocks, since they're just part of the disk format now due to a historic lack of log atomicity. - Don't allow SWAPEXT between files with different [ugp]id when quotas are enabled. - Refactor inode fork reading and verification to run directly from the inode-from-disk function. This means that we now actually guarantee that _iget'ted inodes are totally verified and ready to go. - Move the incore inode fork format and extent counts to the ifork structure. - Scalability improvements by reducing cacheline pingponging in struct xfs_mount. - More scalability improvements by removing m_active_trans from the hot path. - Fix inode counter update sanity checking to run /only/ on debug kernels. - Fix longstanding inconsistency in what error code we return when a program hits project quota limits (ENOSPC). - Fix group quota returning the wrong error code when a program hits group quota limits. - Fix per-type quota limits and grace periods for group and project quotas so that they actually work. - Allow extension of individual grace periods. - Refactor the non-reclaim inode radix tree walking code to remove a bunch of stupid little functions and straighten out the inconsistent naming schemes. - Fix a bug in speculative preallocation where we measured a new allocation based on the last extent mapping in the file instead of looking farther for the last contiguous space allocation. - Force delalloc writes to unwritten extents. This closes a stale disk contents exposure vector if the system goes down before the write completes. - More lockdep whackamole. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAl7OjhgACgkQ+H93GTRK tOuGeBAApuP9ohtvrJT9FW7U+OrRsK3lw/3R+MEYpJu8GKLpGbJ6j+SKrTHxxLvu Rp63YLIlHBOz2rNa4brm/wW8gGJIGXOnGpuiGq0Irl01xEmwqmjOLfLcYkYhno1E i+rG0PiKYZeo/xhLtTKGl+NAwHHxmbOmxUtYHnbinHtPzDyYLQ0wff+oUkmQ7ydg bMYFMXohoJ3Pc5UjmUrCuJj1cvYOUwl0P4LGKiq5Zud61AkBCSskEpk+oo5xFcEX JJc1xkn5MPi+oGpSYqhnSZ6aSjwp53/i44O9volp5vCRXXv1eLVni2u/ScZ85L72 HXxoDyuZOUupirIfMBQFHsazDGPGyFIqtPhGlXoTJjrwX+ymimY6CU/0e+Xu9DEu krlxajfUssH30zyG2q/2TaxslU35CROH6hVBXFe0Y5cEEsOIf2aOpErUhhw2YyS7 onN9gb2NBBQdYtHqIMwsbhcgq60g5H6JfGriB5dJimXXLmpuTfAREGCY2AqIoB1x +8QFod0WwsMn6FYhi/UpZjC9qp/WTvojBUEt8Ci3ketUFwO1CLf9qm6Hj71RL3fs fCEDHx/ZMMft7Bdbf36lICoMAhF/KfNcRn1PsQdpW4LY1Aml/7qjFNZthSVRDW+E rhzNu+RIzGEQsSemBvccRaaTP3HFqN+qPATu2K0sALaa1LRFxzQ= =/NYc -----END PGP SIGNATURE----- Merge tag 'xfs-5.8-merge-8' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "Most of the changes this cycle are refactoring of existing code in preparation for things landing in the future. We also fixed various problems and deficiencies in the quota implementation, and (I hope) the last of the stale read vectors by forcing write allocations to go through the unwritten state until the write completes.
