Hi Andrew,
Please queue the following changes for the next merge window:
Julia Lawall (1): nilfs2: drop null test before destroy functions
Ryusuke Konishi (6): nilfs2: use nilfs_warning() in allocator implementation nilfs2: do not call nilfs_mdt_bgl_lock() needlessly nilfs2: refactor nilfs_palloc_find_available_slot() nilfs2: get rid of nilfs_palloc_group_is_in() nilfs2: add helper functions to delete blocks from dat file nilfs2: free unused dat file blocks during garbage collection
* Brief summary
> nilfs2: drop null test before destroy functions
This removes null tests before calling kmem_cache_destroy() function.
> nilfs2: use nilfs_warning() in allocator implementation > nilfs2: do not call nilfs_mdt_bgl_lock() needlessly > nilfs2: refactor nilfs_palloc_find_available_slot() > nilfs2: get rid of nilfs_palloc_group_is_in()
These are for refactoring bitmap based object allocator/deallocator (alloc.c).
> nilfs2: add helper functions to delete blocks from dat file > nilfs2: free unused dat file blocks during garbage collection
These resolve decline of the available disk space due to bloat of DAT metadata file.
Thanks, Ryusuke Konishi --
