* btrfs-progs: skip fs with no seed when build seed/sprout mapping for fi showGui Hecheng2014-12-04
| | | | | | | | | | | There is no need to try to build seed/sprout mapping for those btrfs without seed devices, so just skip such fs. We could get the total number of devices from the disk super block, if it equals the number of items in list @fs_devices->devices, then there shouldn't be any seed devices.

* btrfs-progs: apply realpath for btrfs fi show when mount point is givenGui Hecheng2014-11-27
| | | | | | | | | | | | | | | | For now, # btrfs fi show /mnt/btrfs gives info correctly, while # btrfs fi show /mnt/btrfs/ gives nothing.

* btrfs-progs: optimize btrfs_scan_lblkid() for multiple callsAnand Jain2014-11-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | btrfs_scan_lblikd() is called by most the device related command functions. And btrfs_scan_lblkid() is most expensive function and it becomes more expensive as number of devices in the system increase. Further some threads call this function more than once for absolutely no extra benefit and the real waste of resources. Below list of threads and number of times btrfs_scan_lblkid() is called in that thread. btrfs-find-root 1 btrfs rescue super-recover 2 btrfs-debug-tree 1 btrfs-image -r 2 btrfs check 2 btrfs restore 2 calc-size NC btrfs-corrupt-block NC btrfs-image NC btrfs-map-logical 1 btrfs-select-super NC btrfstune 2 btrfs-zero-log NC tester NC quick-test.c NC btrfs-convert 0 mkfs #number of devices to be mkfs btrfs label set unmounted 2 btrfs get label unmounted 2 This patch will: move out calling register_one_device with in btrfs_scan_lblkid() and so function setting the BTRFS_UPDATE_KERNEL to yes will call btrfs_register_all_devices() separately. introduce a global variable scan_done, which is set when scan is done succssfully per thread. So that following calls to this function will just return success. Further if any function needs to force scan after scan_done is set, then it can be done when there is such a requirement, but as of now there isn't any such requirement.

* btrfs-progs: Fix number of arguments check of 'btrfs fi df'Qu Wenruo2014-11-03
| | | | | | | | | | | | | | | | 'btrfs fi df' needs exactly one arguments as mount option, but as 3.17 we can run 'btrfs fi df' without any argument, and it will error as "ERROR: can't access '%s'" which means the argument number does not do what it should. The bug is caused by manually modify the optind and use check_argc_max() instead of the original check_argc_exact(). This patch fixes it by not modifying the optind and use check_argc_exact() again.

| | | | | | | | | | | | | | | We can scan for btrfs devices in a few ways. By default libblkid is used for "device scan" and "filesystem show"; with the -m option only mounted filesystems are scanned, and with -d we physically read every system device. But there's no reason for the complexity of a descent through /dev; /proc/partitions has every device known to the kernel, so just use that when -d is specified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | btrfs progs has to scan for the btrfs disks for two main reasons, one to register them with the btrfs kernel (under btrfs dev scan) 2nd to report btrfs disks to the user (under btrfs fi show) (there few more minor reasons like check_mounted etc..). To facilitate the scan, in total we have the following methods to scan for the btrfs BTRFS_SCAN_PROC which uses the /proc/partitions to look for the disks, when scanning it does it twice first would look for non dm- paths and in the 2nd scan it would pick only dm- paths. BTRFS_SCAN_DEV which scans all the block dev under /dev as they appear during scanning. BTRFS_SCAN_LBLKID this uses the library functions provided by the lblkid to get only disks which contains the btrfs SB. The better method to use would be BTRFS_SCAN_LBLKID for the obvious reasons we don't have to reinvent that feature with in btrfs-progs. For the btrfs fi show - This patch will.. - make BTRFS_SCAN_LBLKID as the default scan option (BTRFS_SCAN_DEV is accessible under the option --all-devices and BTRFS_SCAN_PROC won't be used by btrfs fi show any more) Signed-off-by: Anand Jain <anand.jain@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Chris Mason <chris.mason@fusionio.com>
