X-Git-Tag: firefly_0821_release~19682^2~51
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=31b481dc7c249eac0a108ec5dfc0d4aef2217e39;p=firefly-linux-kernel-4.4.55.git

ext4: Fix ext4_mb_init_cache return error

ext4_mb_init_cache() incorrectly always return EIO on success. This
causes the caller of ext4_mb_init_cache() fail when it checks the return
value.
