Subject: bcache: remove redundant LIST_HEAD(journal) from run_cache_set()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=cdca22bcbc64fc83dadb8d927df400a8d86ddabb;p=openwrt%2Fstaging%2Fblogic.git

bcache: remove redundant LIST_HEAD(journal) from run_cache_set()

Commit 95f18c9d1310 ("bcache: avoid potential memleak of list of
journal_replay(s) in the CACHE_SYNC branch of run_cache_set") forgets
to remove the original define of LIST_HEAD(journal), which makes
the change no take effect. This patch removes redundant variable
LIST_HEAD(journal) from run_cache_set(), to make Shenghui's fix
working.
