* Btrfs-progs: added "btrfs quota rescan" -w switch (wait)Jan Schmidt2013-09-03
| | | | | | | | | | With -w one can wait for a rescan operation to finish. It can be used when starting a rescan operation or later to wait for the currently running rescan operation to finish. Waiting is interruptible. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
* Btrfs-progs: fix closing of opendir()Wang Shilong2013-08-09
| | | | | | | | | | valgrind complains open_file_or_dir() causes a memory leak.That is because if we open a directoy by opendir(), and then we should call closedir() to free memory.

* Btrfs-progs: quota rescanJan Schmidt2013-04-23
| | | | | | | | This adds the quota rescan command to be used if qgroup tracking should get out of sync. Can also be used to query the status of a running rescan operation. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
* btrfs-progs: add quota-related info to usage messagesKoen De Wit2013-04-23
| | | | | | | | | | | Extending usage messages with some info on the quota functionality: - The -i option of "subvol create" and "subvol snapshot" was not documented - The -c option of "qgroup limit" is the default option - The "qouta rescan" command is not yet implemented, while it should be executed after enabling quota on a non-empty filesystem.

* Btrfs-progs: move open_file_or_dir() to utils.cAnand Jain2013-01-30
| | | | | | | | | | | The definition of the function open_file_or_dir() is moved from common.c to utils.c in order to be able to share some common code between scrub and the device stats in the following step. That common code uses open_file_or_dir(). Since open_file_or_dir() makes use of the function dirfd(3), the required XOPEN version was raised from 6 to 7.
