Subject: ext4: remove obsoleted check
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=236f5ecb4a5876977837376729a7599cc1ab2cc3;p=deliverable%2Flinux.git

ext4: remove obsoleted check

BH can not be NULL at this point, ext4_read_dirblock() always return
non null value, and we already have done all necessery checks.
