* btrfs-progs: Rename OPEN_CTREE_FS_PARTIAL to OPEN_CTREE_TEMPORARY_SUPERQu Wenruo2018-04-24
| | | | | | | | | | | | | | | | | | | | | | | | The old flag OPEN_CTREE_FS_PARTIAL is in fact quite easy to be confused with OPEN_CTREE_PARTIAL, which allow btrfs-progs to open damaged filesystem (like corrupted extent/csum tree). However OPEN_CTREE_FS_PARTIAL, unlike its name, is just allowing btrfs-progs to open fs with temporary superblocks (which only has 6 basic trees on SINGLE meta/sys chunks). The usage of FS_PARTIAL is really confusing here. So rename OPEN_CTREE_FS_PARTIAL to OPEN_CTREE_TEMPORARY_SUPER, and add extra comment for its behavior. Also rename BTRFS_MAGIC_PARTIAL to BTRFS_MAGIC_TEMPORARY to keep the naming consistent. And with above comment, the usage of FS_PARTIAL in dump-tree is obviously incorrect, fix it.

| | | | | | | | | | Instead of struct btrfs_root, use struct btrfs_fs_info, since nodesize is now a per-fs setting, and with the need to pass a @root, caller don't need to wonder which root should be passed.

* btrfs-progs: Introduce btrfs_raid_array and related infrastructuresQu Wenruo2018-02-24
| | | | | | | | | | | As part of the effort to unify code and behavior between btrfs-progs and kernel, copy the btrfs_raid_array from kernel to btrfs-progs.

No longer root->leafsize. 2) Remove @leafsize parameter from btrfs_setup_root() function Since no root->leafsize, no need for @leafsize parameter. The remaining user of leafsize will be: 1) btrfs inspect-internal dump-super Reformat the "leafsize" output to "leafsize (deprecated)" and use le32_to_cpu() to do the cast manually. 2) mkfs We still need to set sb->__unused_leafsize to nodesize.

* btrfs-progs: convert: Rework rollbackQu Wenruo2017-03-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rework rollback to a more easy to understand way. New convert behavior makes us to have a more flex chunk layout, which only data chunk containing old fs data will be at the same physical location, while new chunks (data/meta/sys) can be mapped anywhere else. This behavior makes old rollback behavior can't handle it. As old behavior assumes all data/meta is mapped in a large chunk, which is mapped 1:1 on disk. So rework rollback to handle new convert behavior, enhance the check by only checking all file extents of convert image, only to check if these file extents and therir chunks are mapped 1:1. This new rollback check behavior can handle both new and old convert behavior, as the new behavior is a superset of old behavior. Further more, introduce a simple rollback mechanisim: 1) Read reserved data (offset = file offset) from convert image 2) Write reserved data into disk (offset = physical offset) Since old fs image is a valid fs, and we only need to rollback superblocks (btrfs reserved ranges), then we just read out data in reserved range, and write it back. Due to the fact that all other file extents of converted image is mapped 1:1 on disk, we put the missing piece back, then the fs is as good as old one. Then what we do in btrfs is just another dream. With this new rollback mechanisim, we can open btrfs read-only, so we won't cause any damage to current btrfs, until the final piece (0~1M, containing 1st super block) is put back.
