Subject: VFS: Use GFP_NOFS in posix_acl_from_xattr()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ab201832f75f58c8f5093436363f80ffa4a4c9a8;p=openwrt%2Fstaging%2Fblogic.git

VFS: Use GFP_NOFS in posix_acl_from_xattr()

GFS2 needs to call this from under a glock, so we need GFP_NOFS
and I suspect that other filesystems might require this too.
