Message-id: <001001cf7fcc$34f3c2c0$9edb4840$@samsung.com> Date: Wed, 04 Jun 2014 17:08:45 +0900 From: Namjae Jeon <namjae.jeon@...sung.com> To: Theodore Ts'o <tytso@....edu> Cc: linux-ext4 <linux-ext4@...r.kernel.org>, Ashish Sangwan <a.sangwan@...sung.com> Subject: [PATCH] ext4: fix COLLAPSE RANGE test failure when bigalloc is enable Blocks in collapse range should be collapsed per cluster unit when bigalloc is enable. If bigalloc is not enable, EXT4_CLUSTER_SIZE will be same with EXT4_BLOCK_SIZE.
