[PATCH] generic/423: statx mask of the reference file is different from the original file

[PATCH] generic/423: statx mask of the reference file is different from the original file

[Cui Yue]

When running xfstests generic/423 to test system call statx() on hard link files of NFS, it fails.
error message:
[!] attr 'stx_mask' differs from ref file, 7ff != e0

The values of parameter "mask" between the original file and the reference file are different.
One is STATX_ALL;
The other is STATX_ATIME | STATX_BTIME | STATX_CTIME | STATX_MTIME.

Modify the function get_reference() to pass the "mask" in,
and change STATX_ATIME | STATX_BTIME | STATX_CTIME | STATX_MTIME to "mask".

Thanks for the fix! Patch looks fine to me, but please follow the kernel
rules for submitting patches in the future. The commit log has too long
lines and you're missing Signed-off-by tag. I'll do the update at commit
time, no need to resend.

Thanks,
Eryu

As remindered by Darrick (thanks Darrick!), I need an explicit SOB tag
from you. Could You please either resend the patch with proper SOB tag
or provide the SOB tag by replying this thread?

Thanks,
Eryu
