f2fs: compress: fix to update isize when overwriting compressed file
We missed to update isize of compressed file in write_end() with below case: cluster size is 16KB - write 14KB data from offset 0 - overwrite 16KB data from offset 0 Fixes: 4c8ff7095bef ("f2fs: support data compression") Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
