Series [V2,1/2] xfs/529: Execute chown on an existing directory entry | expand

Commit Message

Chandan Babu R April 2, 2021, 2:49 a.m. UTC 
xfs/{529,531,532,534,535} attempt to create test files after injecting
reduce_max_iextents error tag. Creation of test files fails when using a
multi-block directory test configuration because,

1. A directory can have a pseudo maximum extent count of 10.
2. In the worst case a directory entry creation operation can consume
   (XFS_DA_NODE_MAXDEPTH + 1 + 1) * (Nr fs blocks in a single directory block)
   extents.
   With 1k fs block size and 4k directory block size, this evaluates to,
   (5 + 1 + 1) * 4
   = 7 * 4
   = 28
   > 10 (Pseudo maximum inode extent count).

This commit fixes the issue by creating test files before injecting
reduce_max_iextents error tag.
