Subject: jbd2: remove repeated assignments in __jbd2_log_wait_for_space()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=fb203751099eecf145317685ee480a51e5b246de;p=linux.git

jbd2: remove repeated assignments in __jbd2_log_wait_for_space()

At the beginning, nblocks has been assigned. There is no need
to repeat the assignment in the while loop, and remove it.
