Subject: [PATCH 4.18 042/123] ext4: use ext4_warning() for sb_getblk failure

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

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

From: Wang Shilong <wshilong@....com>

commit 5ef2a69993676a0dfd49bf60ae1323eb8a288366 upstream.

Out of memory should not be considered as critical errors; so replace
ext4_error() with ext4_warnig().
