Subject: [PATCH -next] mm/madvise: Remove set but not used variable 'zone'
Date: Thu, 17 Sep 2020 15:17:57 +0800 [thread overview]
Message-ID: <20200917071757.1915501-1-liushixin2@huawei.com> (raw)
Fixes gcc '-Wunused-but-set-variable' warning:
mm/madvise.c: In function 'madvise_inject_error':
mm/madvise.c:882:15: warning: unused variable 'zone' [-Wunused-variable]
After 4b63fdbe2b25 ("mm: remove the now-unnecessary mmget_still_valid()
hack"), variable 'zone' is never used. Remove it to avoid build warning.
