f2fs: avoid returning uninitialized value to userspace from f2fs_trim_fs() If user specifies too low end sector for trimming, f2fs_trim_fs() will use uninitialized value as a number of trimmed blocks and returns it to userspace. Initialize number of trimmed blocks early to avoid the problem. Coverity-id: 1248809 CC: stable@vger.kernel.org Signed-off-by: Jan Kara <jack@suse.cz> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
