xfs: convert btree cursor ag-private member name

2020-03-13T17:37:14Z

bc_private.a -> bc_ag conversion via script: `sed -i 's/bc_private\.a/bc_ag/g' fs/xfs/*[ch] fs/xfs/*/*[ch]` And then revert the change to the bc_ag #define in fs/xfs/libxfs/xfs_btree.h manually.

xfs: remove unused header files

2019-06-29T02:30:43Z

There are many, many xfs header files which are included but unneeded (or included twice) in the xfs code, so remove them. nb: xfs_linux.h includes about 9 headers for everyone, so those explicit includes get removed by this. I'm not sure what the preference is, but if we wanted explicit includes everywhere, a followup patch could remove those xfs_*.h includes from xfs_linux.h and move them into the files that need them. Or it could be left as-is. Signed-off-by: Eric Sandeen Reviewed-by: Darrick J. Wong Signed-off-by: Darrick J. Wong

xfs: inode btree scrubber should calculate im_boffset correctly

2019-06-03T16:18:40Z

The im_boffset field is in units of bytes, whereas XFS_INO_OFFSET returns a value in units of inodes. Convert the units so that scrub on a 64k-block filesystem works correctly. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: collapse scrub bool state flags into a single unsigned int

2019-04-16T17:01:57Z

Combine all the boolean state flags in struct xfs_scrub into a single unsigned int, because we're going to be adding more state flags soon. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner

xfs: fix uninitialized error variable

2019-02-21T15:55:07Z

A previous commit removed the initialization of variable 'error' to zero, and can cause a bogus error return. This occurs when error contains a non-zero garbage value and the call to xchk_should_terminate detects a pending fatal signal and checks for a zero error before setting it to -EAGAIN. Fix the issue by initializing error to zero. Fixes: b9454fe056bd ("xfs: clean up the inode cluster checking in the inobt scrub") Signed-off-by: Colin Ian King Reviewed-by: Darrick J.

xfs: consolidate scrub dinode mapping code into a single function

2019-02-12T00:06:39Z

Move all the confusing dinode mapping code that's split between xchk_iallocbt_check_cluster and xchk_iallocbt_check_cluster_ifree into the first function so that it's clearer how we find the dinode for a given inode. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: scrub big block inode btrees correctly

2019-02-12T00:06:39Z

Teach scrub how to handle the case that there are one or more inobt records covering a given inode cluster. This fixes the operation on big block filesystems (e.g. 64k blocks, 512 byte inodes). Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: clean up the inode cluster checking in the inobt scrub

2019-02-12T00:06:39Z

The code to check inobt records against inode clusters is a mess of poorly named variables and unnecessary parameters. Clean the unnecessary inode number parameters out of _check_cluster_freemask in favor of computing them inside the function instead of making the caller do it. In xchk_iallocbt_check_cluster, rename the variables to make it more obvious just what chunk_ino and cluster_ino represent. Add a tracepoint to make it easier to track each inode cluster as we scrub it. Signed-off-by: Darrick J. Wong Reviewed-by: Brian Foster

xfs: hoist inode cluster checks out of loop

2019-02-12T00:06:39Z

Hoist the inode cluster checks out of the inobt record check loop into a separate function in preparation for refactoring of that loop. No functional changes here; that's in the next patch. Signed-off-by: Darrick J. Wong Reviewed-by: Dave Chinner Reviewed-by: Brian Foster
