xfs: remove conditional building of rt geometry validator functions I mistakenly turned off CONFIG_XFS_RT in the Kconfig file for arm64 variant of the djwong-wtf git branch. Unfortunately, it took me a good hour to figure out that RT wasn't built because this is what got printed to dmesg: XFS (sda2): realtime geometry sanity check failed XFS (sda2): Metadata corruption detected at xfs_sb_read_verify+0x170/0x190 [xfs], xfs_sb block 0x0 Whereas I would have expected: XFS (sda2): Not built with CONFIG_XFS_RT XFS (sda2): RT mount failed The root cause of these problems is the conditional compilation of the new functions xfs_validate_rtextents and xfs_compute_rextslog that I introduced in the two commits listed below. The !RT versions of these functions return false and 0, respectively, which causes primary superblock validation to fail, which explains the first message. Move the two functions to other parts of libxfs that are not conditionally defined by CONFIG_XFS_RT and remove the broken stubs so that validation works again.

xfs: check rt bitmap file geometry more thoroughly I forgot that the superblock tracks the number of blocks that are in the realtime bitmap, and that the rt bitmap file can have more blocks mapped to the data fork than sb_rbmblocks if growfsrt fails. So. Add to the rtbitmap scrubber an explicit check that sb_rextents and sb_rbmblocks are correct, then adjust the rtbitmap i_size checks to allow for the growfsrt failure case. Finally, flag post-eof blocks in the rtbitmap. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>

xfs: try to attach dquots to files before repairing them Inode resource usage is tracked in the quota metadata. Repairing a file might change the resources used by that file, which means that we need to attach dquots to the file that we're examining before accessing anything in the file protected by the ILOCK. However, there's a twist: a dquot cache miss requires the dquot to be read in from the quota file, during which we drop the ILOCK on the file being examined. This means that we *must* try to attach the dquots before taking the ILOCK. Therefore, dquots must be attached to files in the scrub setup function. If doing so yields corruption errors (or unknown dquot errors), we instead clear the quotachecked status, which will cause a quotacheck on next mount. A future series will make this trigger live quotacheck. While we're here, change the xrep_ino_dqattach function to use the unlocked dqattach functions so that we avoid cycling the ILOCK if the inode already has dquots attached. This makes the naming and locking requirements consistent with the rest of the filesystem. Signed-off-by: Darrick J. Wong <djwong@kernel.org> Reviewed-by: Christoph Hellwig <hch@lst.de>

xfs: convert xfs_extlen_t to xfs_rtxlen_t in the rt allocator In most of the filesystem, we use xfs_extlen_t to store the length of a file (or AG) space mapping in units of fs blocks. Unfortunately, the realtime allocator also uses it to store the length of a rt space mapping in units of rt extents. This is confusing, since one rt extent can consist of many fs blocks. Separate the two by introducing a new type (xfs_rtxlen_t) to store the length of a space mapping (in units of realtime extents) that would be found in a file. Signed-off-by: Darrick J.
