Subject: UBIFS: remove unnecessary code in ubifs_garbage_collect
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=e71d1a59e757201454fd3cf66ddaceaf961bfb41;p=deliverable%2Flinux.git

UBIFS: remove unnecessary code in ubifs_garbage_collect

In ubifs_garbage_collect,local variable "space_before" calculate twice. In
fact, at the beginning of the loop, there is no need to calculate this
variable. Calculate it before call "ubifs_garbage_collect_leb" is enough. This
patch just remove the unnecessary calculate code.
