Jie Liu 7cddc19392 btrfs: fix file truncation if FALLOC_FL_KEEP_SIZE is specified ... Create a small file and fallocate it to a big size with FALLOC_FL_KEEP_SIZE option, then truncate it back to the small size again, the disk free space is not changed back in this case. i.e, total 4 -rw-r--r-- 1 root root 512 Jun 28 11:35 test Filesystem Size Used Avail Use% Mounted on .... /dev/sdb1 8.0G 56K 7.2G 1% /mnt -rw-r--r-- 1 root root 512 Jun 28 11:35 /mnt/test Filesystem Size Used Avail Use% Mounted on .... /dev/sdb1 8.0G 5.1G 2.2G 70% /mnt Filesystem Size Used Avail Use% Mounted on .... /dev/sdb1 8.0G 5.1G 2.2G 70% /mnt With this fix, the truncated up space is back as: Filesystem Size Used Avail Use% Mounted on .... /dev/sdb1 8.0G 56K 7.2G 1% /mnt Signed-off-by: Jie Liu <jeff.liu@oracle.com> Signed-off-by: Josef Bacik <jbacik@fusionio.com> Signed-off-by: Chris Mason <chris.mason@fusionio.com>		2013-08-09 19:28:56 -04:00
