Subject: [PATCH 4/6] xfs/532: Fix test to execute in multi-block directory config
Date: Thu, 25 Mar 2021 19:38:55 +0530
Message-ID: <20210325140857.7145-4-chandanrlinux@gmail.com> (raw)
In-Reply-To: <20210325140857.7145-1-chandanrlinux@gmail.com>

xfs/532 attempts to create $testfile after reduce_max_iextents error tag is
injected. Creation of $testfile 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 $testfile before injecting
reduce_max_iextents error tag.
