2020-03-23btrfs: introduce per-inode file extent treeJosef Bacik
In order to keep track of where we have file extents on disk, and thus where it is safe to adjust the i_size to, we need to have a tree in place to keep track of the contiguous areas we have file extents for. Add helpers to use this tree, as it's not required for NO_HOLES file systems. We will use this by setting DIRTY for areas we know we have file extent item's set, and clearing it when we remove file extent items for truncation.

2019-11-18btrfs: move the failrec tree stuff into extent-io-tree.hJosef Bacik
This needs to be cleaned up in the future, but for now it belongs to the extent-io-tree stuff since it uses the internal tree search code. Needed to export get_state_failrec and set_state_failrec as well since we're not going to move the actual IO part of the failrec stuff out at this point.

2019-11-18btrfs: export find_delalloc_rangeJosef Bacik
This utilizes internal stuff to the extent_io_tree, so we need to export it before we move it. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
2019-11-18btrfs: move extent_io_tree defs to their own headerJosef Bacik
extent_io.c/h are huge, encompassing a bunch of different things. The extent_io_tree code can live on its own, so separate this out. Signed-off-by: Josef Bacik <josef@toxicpanda.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
