[PATCH v2 0/4] xfstests: add parent pointer tests

[PATCH v2 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/20220922054458.40826-1-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.

v1->v2:
- Print name and length of bad parent pointer
- Remove line that explicitly turns on LARP mode
- Remove unnecessary empty lines
- Split single patch into multiple patches
- Add _require_xfs_parent function
- Check that mkfs/kernel/xfs_io supports parent pointers

Comments and feedback appreciated!

Catherine

[PATCH v2 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.

This's same with common cleanup function, you can remove this function.

What's this function for? I didn't see this function is called in this case.
Am I missing something?

It just writes a general file, right? Is there any special reason might cause
write fail?

I think we don't need to check each step's return value. And if we fail to write
a file, bash helps to output error message to break golden image too.

And does this case really do error injection? I didn't find that. If not, please
remove this requirement and above common/inject. Same question for patch 4.

Ok, these tests were initially written before these helpers were
hoisted into a common location, so it makes sense to clean them out
now.

I think it's another common helper that's over in common/log now.  I
suspect it was just reminiscent of the test case I modeled this after
at the time.  It should likely come out now too.

I think I had borrowed this from the protofile test case
(tests/xfs/019).  But yes, if the file creation were to fail, I think
the mkfs command will just error out.  It should be fine to take it out
if folks prefer.  Thanks for the reviews!

I think at one point I had all these tests in one file and then later
separated them into multiple tests.  So I think the requirements for
