This change is buggy. I had already posted it and self NACKed myself [1].
You can find an hopefully non-buggy version of it on my ovl-shutdown [2] branch.
As long as you are changing ovl_ioctl(), please also take the second
commit on that
branch to replace the open coded capability check with the
vfs_ioc_setflags_prepare()
generic helper.
Hi Amir,
Thanks a lot for your quick reply. :-)
I will try to read and understand the metioned patches on your
ovl-shutdown branch.
Please also verify my claim in the patch commit message, that the
the test result of xfstest generic/079 changes from "notrun" to "success".
Hi Amir,
With your patches, I have confirmed that generic/079 actually changed from
"notrun" to "success". Besides, one minor issue:
Could we avoid the following compiler warning?
-------------------------------------------------
fs/overlayfs/readdir.c: In function ‘ovl_dir_real_file’:
fs/overlayfs/readdir.c:883:37: warning: passing argument 1 of
‘ovl_dir_open_realfile’ discards ‘const’ qualifier from pointer target

Thanks,
