* btrfs-progs: Add helpers functions to handle the printing of data in tabular ↵Goffredo Baroncelli2014-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | format This patch adds some functions to manage the printing of the data in tabular format. The function struct string_table *table_create(int columns, int rows) creates an (empty) table. The functions char *table_printf(struct string_table *tab, int column, int row, char *fmt, ...) char *table_vprintf(struct string_table *tab, int column, int row, char *fmt, va_list ap) populate the table with text. To align the text to the left, the text shall be prefixed with '<', otherwise the text shall be prefixed by a '>'. If the first character is a '=', the the text is replace by a sequence of '=' to fill the column width. The function void table_free(struct string_table *) frees all the data associated to the table. The function void table_dump(struct string_table *tab) prints the table on stdout. Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.cz>

* 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.

| | | | | | | | | | | | | | | | If you exec: # btrfs sub show <dir> <== non-subvolume dir The cmd print error messages as expected, but returns 0. By convetion, it should return non-zero and we should explicitly set it before it goto out. With other pieces adopted: 1) removed a unnecessary return value set -EINVAL 2) fixed another code branch which may return 0 upon error. 3) with 2) applied, the ret = 0 follows can be removed Signed-off-by: Gui Hecheng <guihc.fnst@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.cz>

* Btrfs-progs: fix a bug of converting sparse ext2/3/4Liu Bo2014-11-25
| | | | | | | | | | | | When converting a sparse ext* filesystem, btrfs-convert adds checksum extents for empty extents, whose disk_bytenr = 0, and this can end up with some weird problems, one of them is the failure of reading free space cache inode on mounting converted btrfs. The fix is simple, just to skip making checksum on empty extents. Signed-off-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: David Sterba <dsterba@suse.cz>

* 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.
