[PATCH v3 0/1] xfstests: add log attribute replay test

[PATCH v3 0/1] xfstests: add log attribute replay test

[Catherine Hoang]

Hi all,

This patch aims to provide better test coverage for Allison’s delayed
attribute set. These tests aim to cover cases where attributes are added,
removed, and overwritten in each format (shortform, leaf, node). Error
inject is used to replay these operations from the log.

Since v2, the following tests have been added:
- empty, add/remove inline attr         (64 bytes)
- empty, add/remove internal attr	     (1kB)
- empty, add/remove remote attr	     (64kB)
- inline, add/remove inline attr           (64 bytes)
- inline, add/remove internal attr	     (1kB)
- inline, add/remove remote attr	     (64kB)
- extent, add/remove internal attr	     (1kB)
- extent, add multiple internal attr      (inject error on split operation)
- extent, add multiple internal attr      (inject error on transition to node)
- extent, add/remove remote attr	     (64kB)
- btree, add/remove multiple internal (1kB)
- btree, add/remove remote attr         (64kB)
- overwrite shortform attr
- overwrite leaf attr
- overwrite node attr 

Running these tests require the new error tags leaf_split and leaf_to_node,
which can also be found on Allison’s github trees.

[PATCH v3 1/1] xfstests: Add Log Attribute Replay test

[Catherine Hoang]

From: Allison Henderson <allison.henderson@oracle.com>

This patch adds tests to exercise the log attribute error
inject and log replay. These tests aim to cover cases where attributes
are added, removed, and overwritten in each format (shortform, leaf,
node). Error inject is used to replay these operations from the log.

No need to umount scratch dev, the test harness will umount it.

The leading underscore can be removed, that's for common helper
functions.

Should do _filter_scratch on stderr as well, otherwise it prints the raw
$SCRATCH_MNT into golden output on error.

No need to umount, scratch dev is not mounted at the start of each test.

Just _scratch_mkfs should be fine.
