[PATCH 4.4 018/143] f2fs: fix wrong return value of f2fs_acl_create

From: Greg Kroah-Hartman
Date: Mon Feb 18 2019 - 09:01:38 EST


4.4-stable review patch. If anyone has any objections, please let me know.

------------------

[ Upstream commit f6176473a0c7472380eef72ebeb330cf9485bf0a ]

When call f2fs_acl_create_masq() failed, the caller f2fs_acl_create()
should return -EIO instead of -ENOMEM, this patch makes it consistent
with posix_acl_create() which has been fixed in commit beaf226b863a
("posix_acl: don't ignore return value of posix_acl_create_masq()").

Fixes: 83dfe53c185e ("f2fs: fix reference leaks in f2fs_acl_create")
