# FS QA Test No. 486
#
# Ensure that we can XATTR_REPLACE a tiny attr into a large attr.
# Kanda Motohiro <kanda.motohiro@gmail.com> reports that XATTR_REPLACE'ing
# a single-byte attr with a 2048-byte attr causes a fs shutdown because we
# remove the shortform attr, convert the attr fork to long format, and then
# try to re-add the attr having not cleared ATTR_REPLACE.
#
# Commit 7b38460dc8e4 ("xfs: don't fail when converting shortform attr to long
# form during ATTR_REPLACE") fixed the xfs bug.
