* btrfs-progs: util: Fix a wrong unit of pretty_sizeQu Wenruo2016-03-14
| | | | | | | | | | | | | | | | | If parameter for pretty_size is smaller than default base(1024), pretty_size() will output wrong unit. For example, pretty_size(1008) will output '0.98B' not '1008B' or '0.98KiB'. The cause is, for default base and auto-detect unit, base will be 1024 but num_divs is still 0, last result will still be divided by base, causing the bug. Fix it by checking num_divs in default case, and if num_divs is 0, change base to 1. Signed-off-by: Qu Wenruo <quwenruo@cn.fujitsu.com> Signed-off-by: David Sterba <dsterba@suse.com>

* btrfs-progs: fi du: Calculate space shared by each directory arguments file setMark Fasheh2016-03-14
| | | | | | | | | | | | | | Here we define each file set as those found by a recursive search of a single directory argument to btrfs fi du. This isn't as simple as adding up shared extents - they may be shared with each other, and may also overlap. This patch uses an interval tree to store shared extents we find while fiemapping files. After collecting them, a 'set shared' count is calculated by summing (without overlap) each shared region discovered. This is then displayed to the user as 'set shared'.

* btrfs-progs: filesystem: add 'du' commandMark Fasheh2016-03-14
| | | | | | | | | | | | | | | | | 'btrfs du' differs from regular du in that it will work to resolve which blocks are shared between files in its list. This gives the user a more accurate bytecount from which they can make decisions regarding management of their file space. We still print a total number of bytes counted (like regular du), but also print the number of bytes which were found to have been shared amongst the file set provided. From there it becomes trivial to calculate how much space is exclusively owned.

* btrfs-progs: Allow open_ctree to return fs_info even chunk tree is corruptedQu Wenruo2016-02-26
| | | | | | | | | | | | | | | | | | | | | | | | | Current open_ctree_fs_info() won't return anything if chunk tree root is corrupted. This makes some function, like btrfs-find-root, unable to find any older chunk tree root, even it is possible to use system_chunk_array in super block. And at least two users in mail list has reported such heavily chunk corruption. Although we have 'btrfs rescue chunk-recovery' but it's too time consuming and sometimes not able to cope with a specific filesystem corruption. This patch adds a new open ctree flag, OPEN_CTREE_IGNORE_CHUNK_TREE_ERROR, allowing fs_info to be returned from open_ctree_fs_info() even there is no valid tree root in it. Also adds a new close_ctree() variant, close_ctree_fs_info() to handle possible fs_info without any root.

* btrfs-progs: volume: Fix a bug causing btrfs-find-root to skip first chunkQu Wenruo2016-02-26
| | | | | | | | | | | | | | | There is a small bug from 2011, where btrfs_next_bg (formally btrfs_next_metadata) function will always skip the first chunk. That's OK for that time, as there is always 3 empty temporary chunks. But now, we may ended up with only one metadata or system chunk, with empty chunk auto-remove from kernel or new mkfs.btrfs. So fix it by checking the initial value so btrfs_next_bg() will return the first chunk if its *logical parameter is 0.
