      btrfs: tests: unify messages when tests start · e4fa7469
      David Sterba authored
      
      
      - make the messages more visually consistent and use same format
        "running ... test", any error or other warning can be easily spotted
      
      - move some message to the test entry function
      
      - add message to the inode tests
      
      Example output:

      btrfs: tests/qgroup: Fix wrong tree backref level · 3c0efdf0
      Qu Wenruo authored
      The extent tree of the test fs is like the following:
      
       BTRFS info (device (null)): leaf 16327509003777336587 total ptrs 1 free space 3919
        item 0 key (4096 168 4096) itemoff 3944 itemsize 51
                extent refs 1 gen 1 flags 2
                tree block key (68719476736 0 0) level 1
                                                 ^^^^^^^
                ref#0: tree block backref root 5
      
      And it's using an empty tree for fs tree, so there is no way that its
      level can be 1.
      
      For REAL (created by mkfs) fs tree backref with no skinny metadata, the
      result should look like:
      
       item 3 key (30408704 EXTENT_ITEM 4096) itemoff 3845 itemsize 51
               refs 1 gen 4 flags TREE_BLOCK
               tree block key (256 INODE_ITEM 0) level 0
                                                 ^^^^^^^
               tree block backref root 5
      
      Fix the level to 0, so it won't break later tree level checker.

      btrfs: add a flag to iterate_inodes_from_logical to find all extent refs for uncompressed extents · c995ab3c
      Zygo Blaxell authored
      
      
      The LOGICAL_INO ioctl provides a backward mapping from extent bytenr and
      offset (encoded as a single logical address) to a list of extent refs.
      LOGICAL_INO complements TREE_SEARCH, which provides the forward mapping
      (extent ref -> extent bytenr and offset, or logical address).  These are
      useful capabilities for programs that manipulate extents and extent
      references from userspace (e.g. dedup and defrag utilities).
      
      When the extents are uncompressed (and not encrypted and not other),
      check_extent_in_eb performs filtering of the extent refs to remove any
      extent refs which do not contain the same extent offset as the 'logical'
      parameter's extent offset.  This prevents LOGICAL_INO from returning
      references to more than a single block.
      
      To find the set of extent references to an uncompressed extent from [a, b),
      userspace has to run a loop like this pseudocode:
      
      	for (i = a; i < b; ++i)
      		extent_ref_set += LOGICAL_INO(i);
      
      At each iteration of the loop (up to 32768 iterations for a 128M extent),
      data we are interested in is collected in the kernel, then deleted by
      the filter in check_extent_in_eb.
      
      When the extents are compressed (or encrypted or other), the 'logical'
      parameter must be an extent bytenr (the 'a' parameter in the loop).
      No filtering by extent offset is done (or possible?) so the result is
      the complete set of extent refs for the entire extent.  This removes
      the need for the loop, since we get all the extent refs in one call.
      
      Add an 'ignore_offset' argument to iterate_inodes_from_logical,
      [...several levels of function call graph...], and check_extent_in_eb, so
      that we can disable the extent offset filtering for uncompressed extents.
      This flag can be set by an improved version of the LOGICAL_INO ioctl to
      get either behavior as desired.
      
      There is no functional change in this patch.  The new flag is always
      false.

      Btrfs: add a flags field to btrfs_fs_info · afcdd129
      Josef Bacik authored
      
      
      We have a lot of random ints in btrfs_fs_info that can be put into flags.  This
      is mostly equivalent with the exception of how we deal with quota going on or
      off, now instead we set a flag when we are turning it on or off and deal with
      that appropriately, rather than just having a pending state that the current
      quota_enabled gets set to.  Thanks,

      Btrfs: fix qgroups sanity test crash or hang · b050f9f6
      Filipe Manana authored
      
      
      Often when running the qgroups sanity test, a crash or a hang happened.
      This is because the extent buffer the test uses for the root node doesn't
      have an header level explicitly set, making it have a random level value.
      This is a problem when it's not zero for the btrfs_search_slot() calls
      the test ends up doing, resulting in crashes or hangs such as the following:

      Btrfs: add sanity tests for new qgroup accounting code · faa2dbf0
      Josef Bacik authored
      
      
      This exercises the various parts of the new qgroup accounting code.  We do some
      basic stuff and do some things with the shared refs to make sure all that code
      works.  I had to add a bunch of infrastructure because I needed to be able to
      insert items into a fake tree without having to do all the hard work myself,
      hopefully this will be usefull in the future.  Thanks,
