[PATCH] Btrfs: pass lockdep rwsem metadata to async commit transaction
The freeze rwsem is taken by sb_start_intwrite() and dropped during the
commit_ or end_transaction(). In the async case, that happens in a worker
thread. Tell lockdep the calling thread is releasing ownership of the
rwsem and the async thread is picking it up.
Josef and I worked out a more complicated solution that made the async
commit thread join and potentially get a later transaction, but

[PATCH v0 00/18] btfs: Subvolume Quota Groups
This is a first draft of a subvolume quota implementation. It is possible
to limit subvolumes and any group of subvolumes and also to track the amount
of space that will get freed when deleting snapshots.
The current version is functionally incomplete, with the main missing feature
being the initial scan and rescan of an existing filesystem.
I put some effort into writing an introduction into

[PATCH 00/21] [RFC] Btrfs: restriper
Hello,
This patch series adds an initial implementation of restriper (it''s a
clever name for relocation framework that allows to do selective profile
changing and selective balancing with some goodies like pausing/resuming
and reporting progress to the user.
Profile changing is global (per-FS) so far, per-subvolume profiles
require some discussion and can be implemented in future.
