Amir Goldstein 420332b941 ovl: mark xwhiteouts directory with overlay.opaque='x' ... An opaque directory cannot have xwhiteouts, so instead of marking an xwhiteouts directory with a new xattr, overload overlay.opaque xattr for marking both opaque dir ('y') and xwhiteouts dir ('x'). This is more efficient as the overlay.opaque xattr is checked during lookup of directory anyway. This also prevents unnecessary checking the xattr when reading a directory without xwhiteouts, i.e. most of the time. Note that the xwhiteouts marker is not checked on the upper layer and on the last layer in lowerstack, where xwhiteouts are not expected. Fixes: bc8df7a3dc ("ovl: Add an alternative type of whiteout") Cc: <stable@vger.kernel.org> # v6.7 Reviewed-by: Alexander Larsson <alexl@redhat.com> Tested-by: Alexander Larsson <alexl@redhat.com> Signed-off-by: Amir Goldstein <amir73il@gmail.com>		2024-01-23 12:39:48 +02:00
