From a66c7b2fcfbc9ef4e972f6bc2b63d72d00f23122 Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 22 Nov 2013 16:52:50 +0800 Subject: [PATCH] f2fs: remove unneeded code in punch_hole 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.
