<para>
<command>vfs_linux_xfs_sgid</command> is a VFS module to work around an
old Linux XFS bug fixed in 3.11: the SGID bit is not inherited during mkdir
when a default ACL is set

https://web.archive.org/web/20160320180937/http://oss.sgi.com/bugzilla/show_bug.cgi?id=280
</ulink> fixed by <ulink url="https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=42c49d7f249c2487f36d3314753d5d8ebcee8249">

The <command>vfs_linux_xfs_sgid</command> VFS module will work around this
bug by manually setting the SGID bit after a <command>mkdir</command>
if the parent directory had the SGID bit set.
