Subject: vfs:ceph: Allow VFS_OPEN_HOW_RESOLVE_NO_XDEV flag
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=458fd85d5aa2b3c41a0656b47d8c770c7f6c9957;p=thirdparty%2Fsamba.git

vfs:ceph: Allow VFS_OPEN_HOW_RESOLVE_NO_XDEV flag

Don't return ENOSYS if the flag is set. It will be ignored,
does not make sense in a ceph virtual filesystem.
