Subject: [f2fs-dev] [PATCH] f2fs: remove unneeded code in punch_hole
Date: Fri, 22 Nov 2013 16:52:50 +0800 [thread overview]
Message-ID: <000201cee760$58df9f10$0a9edd30$@samsung.com> (raw)
In-Reply-To:
Because FALLOC_FL_PUNCH_HOLE flag must be ORed with FALLOC_FL_KEEP_SIZE
in fallocate, so we could remove the useless 'keep size' branch code which
will never be excuted in punch_hole.
