* btrfs-progs: inspect rootid: Allow a file to be specifiedMisono, Tomohiro2017-09-08
| | | | | | | | | | | | | Since cmd_inspect_rootid() calls btrfs_open_dir(), it rejects a file to be specified. But as the document says, a file should be supported. This patch introduces btrfs_open_file_or_dir(), which is a counterpart of btrfs_open_dir(), to safely check and open btrfs file or directory. The original btrfs_open_dir() content is moved to btrfs_open() and shared by both function.

* btrfs-progs: print the csum length in debug-treeJosef Bacik2017-09-08
| | | | | | | | | | While looking at a log of a corrupted fs I needed to verify we were missing csums for a given range. Make this easier by printing out the range of bytes a csum item covers.

* btrfs-progs: fi du: don't call lookup_path_rootid for ↵Goffredo Baroncelli2017-09-08
| | | | | | | | | | | | | | | | | | | | | | | BTRFS_EMPTY_SUBVOL_DIR_OBJECTID When ino is BTRFS_EMPTY_SUBVOL_DIR_OBJECTID, the item is not referred to any file-tree. So lookup_path_rootid() doesn't return any meaningful value. As was reported, this can be triggered by $ btrfs sub create test1 $ btrfs sub create test1/test2 $ btrfs sub snap test1 test1.snap $ btrfs fi du -s test1 Total Exclusive Set shared Filename 0.00B 0.00B 0.00B test1 $ btrfs fi du -s test1.snap Total Exclusive Set shared Filename ERROR: cannot check space of 'test1.snap': Inappropriate ioctl for device Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.com>

| | | | | | | | | In du_walk_dir(), when du_add_file() returns an error it is usually ignored. However if the error is returned querying the last item, the error is returned to the caller. Signed-off-by: Goffredo Baroncelli <kreijack@inwind.it> Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: check: add option to skip mount checksDavid Sterba2017-09-08
| | | | | | | | | | | Sometimes it's needed to do a check on a mounted filesystem. This should work fine on a quiescent filesystem or a read-only mount. Changes on the block device done by kernel might confuse the userspace checker and it might crash when it reads some stale data. Repair without mount checks is not supported right now.
