* 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
