Subject: btrfs: remove unnecessary cur_trans set before goto loop in join_transaction
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=210b907acfb414650dcdae9b470eb2fccac7996b;p=linux-beck.git

btrfs: remove unnecessary cur_trans set before goto loop in join_transaction

In the big loop, cur_trans will be set fs_info->running_transaction
before it's used. And after kmem_cache_free it and goto loop, it will
be setup again. No need to setup it immediately after freed.
