* btrfs-progs: Factor out common print_device_infoNikolay Borisov2018-01-31
| | | | | | | | | This function has been copied twice in chunk-recover and super-recover. Factor it out into utils.c/h and use it. No functional changes. Signed-off-by: Nikolay Borisov <nborisov@suse.com> Reviewed-by: Qu Wenruo <wqu@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
* btrfs-progs: mkfs: Use the whole file or block device to mkfs for rootdirQu Wenruo2018-01-08
| | | | | | | | | | | | | | | For --rootdir, even for large existing file or block device, it will always shrink the resulting filesystem. The problem is, mkfs.btrfs will try to calculate the dir size, and use it as @block_count to mkfs, which makes the filesystem shrunk. Fix it by trying to get the original block device or file size as @block_count, so mkfs.btrfs can use the full file/block device for --rootdir option.

* btrfs-progs: mkfs: fix regression preventing --rootdir to create fileQu Wenruo2018-01-08
| | | | | | | | | | | | | | | | Commit 460e93f25754 ("btrfs-progs: mkfs: check the status of file at mkfs") will try to check the file state before creating fs on it. The check is mostly fine for normal mkfs case, while for --rootdir option, it's allowed to create a new file if the destination file doesn't exist. Fix it by allowing non-existent file if --rootdir is specified.

* btrfs-progs: extent-cache: actually cache extent buffersJeff Mahoney2017-10-06
| | | | | | | | | | | | | | We have the infrastructure to cache extent buffers but we don't actually do the caching. As soon as the last reference is dropped, the buffer is dropped. This patch keeps the extent buffers around until the max cache size is reached (defaults to 25% of memory) and then it drops the last 10% of the LRU to free up cache space for reallocation. The cache size is configurable (for use by e.g. lowmem) when the cache is initialized.

* 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: subvol show: add support to search subvolume by rootid or uuidAnand Jain2017-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unless the top level is mounted there is no way to know the details of all the subvolume. For example: mount -o subvol=sv1/newsv1 /dev/sdb /btrfs btrfs su list /btrfs ID 257 gen 12 top level 5 path sv1 ID 258 gen 9 top level 257 path sv1/snap ID 259 gen 11 top level 257 path sv1/newsv1 You can't subvol show for sv1 and sv1/snap as its paths aren't accessible to the user unless the its top level is mounted. This patch adds two new options to the existing btrfs subvol show cli. They are --rootid/-r or --uuid/-u, with this now the user will be able to look for a subvolume using the rootid OR the uuid. ./btrfs su show -r 257 /btrfs sv1 Name: sv1 UUID: 30129358-c69d-3e4a-a662-29509cc69c95 Parent UUID: - Received UUID: - Creation time: 2017-07-11 20:32:57 +0800 Subvolume ID: 257 Generation: 12 Gen at creation: 7 Parent ID: 5 Top level ID: 5 Flags: - Snapshot(s): sv1/snap Signed-off-by: Anand Jain <anand.jain@oracle.com> [ minor adjustments in the help text ] Signed-off-by: David Sterba <dsterba@suse.com>

This will be used to create old filesystem image. 2) struct cache_tree data_chunks Records batched ranges which must be covered by data chunks. The bytenr range is optimized to meet all the chunk requirement. 3) u64 total_bytenr Records how large the filesystem is in bytenr. Yes, we can calculate it easy, but that's for old blocks based filesystem. This will make it more friendly for extent based filesystem. And later cctx->block_counts and may be removed And 2 for mkfs_config: 1) char *chunk_uuid. Used as temporary chunk_uuid (unparsed) string for later make_convert_btrfs() 2) u64 super_bytenr Records the new temporary super bytenr after make_btrfs().
