[PATCH v3 0/4] xfstests: add parent pointer tests

[PATCH v3 0/4] xfstests: add parent pointer tests

[Catherine Hoang]

Hi all,

These are the tests for Allison's parent pointer series:
https://lore.kernel.org/linux-xfs/20221021222936.934426-1-allison.henderson@oracle.com/

These tests cover basic parent pointer operations, multiple links, and
error inject. This patch also adds a new parent group and parent common
functions.

v2->v3:
- Remove old helper functions
- Clean up requirements for each test
- Let mkfs handle protofile errors

Comments and feedback appreciated!

Catherine

[PATCH v3 1/4] common: add helpers for parent pointer tests

[Catherine Hoang]

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

Add helper functions in common/parent to parse and verify parent
pointers. Also add functions to check that mkfs, kernel, and xfs_io
support parent pointers.

Hi,

xfs/554 has been taken, please rebase to the lastest for-next branch, or you
can a big enough number (e.g. 999) to avoid merging conflict, then I can rename

_scratch_mount calls _fail() inside.

Sorry I'm confused about this explanation:) Do you need to read/write the
/sys/fs/xfs/debug/larp in this case? To make sure *parent* feature is 100%
truned on? Can't _require_xfs_parent make sure current system support the

No, you only have to do that if you want ALL attributes to be logged. 
If the fs was created with the parent mkfs option, then parent pointer
attributes (at least) will be logged.  

Unlike normal attrs, parent pointers cannot be toggled.  So once they
are enabled at mkfs time, they will always be logged regardless as to
whether the standard attributes are being logged or not.

Yes, basically the _require_xfs_parent routine ensures the the parent
mkfs option is there and works :-)
