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).
