The patch titled Subject: simple_xattr: permit 0-size extended attributes has been removed from the -mm tree. Its filename was simple_xattr-permit-0-size-extended-attributes.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Hugh Dickins <hughd@xxxxxxxxxx> Subject: simple_xattr: permit 0-size extended attributes If a filesystem uses simple_xattr to support user extended attributes, LTP setxattr01 and xfstests generic/062 fail with "Cannot allocate memory": simple_xattr_alloc()'s wrap-around test mistakenly excludes values of zero size. Fix that off-by-one (but apparently no filesystem needs them yet).
