f2fs: keep isize once block is reserved cross EOF Without FADVISE_KEEP_SIZE_BIT, we will try to recover file size according to last non-hole block, so in fallocate(), we must set FADVISE_KEEP_SIZE_BIT flag once we have preallocated block cross EOF, instead of when all preallocation is success. Otherwise, file size will be incorrect due to lack of this flag. Simple testcase to reproduce this: 1. echo 2 > /sys/fs/f2fs/<device>/inject_type 2. echo 10 > /sys/fs/f2fs/<device>/inject_rate 3. run tests/generic/392 4. disable fault injection 5. do remount Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
