6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhiguo Niu <zhiguo.niu@xxxxxxxxxx>
[ Upstream commit 86d7d57a3f096c8349b32a0cd5f6f314e4416a6d ]
Should check return value of f2fs_recover_xattr_data in
__f2fs_setxattr rather than doing invalid retry if error happen.
Also just do set_page_dirty in f2fs_recover_xattr_data when
page is changed really.
Fixes: 50a472bbc79f ("f2fs: do not return EFSCORRUPTED, but try to run online repair")
