As a preparation for removing ext2 non-atomic bit operations from
asm/bitops.h. This converts ext2 non-atomic bit operations to
little-endian bit operations.Signed-off-by: Akinobu Mita

The implementation of persistent object allocator (alloc.c) is poorly
documented. This adds kernel doc style comments on that functions.Signed-off-by: Ryusuke Konishi

This adds setup and cleanup routines of the persistent object
allocator cache.According to ftrace analyses, accessing buffers of the DAT file
suffers indispensable overhead many times. To mitigate the overhead,
This introduce cache framework for the persistent object allocator
(palloc) which the DAT file and ifile are using.struct nilfs_palloc_cache represents the cache object per metadata
file using palloc.The cache is initialized through nilfs_palloc_setup_cache() and
destroyed by nilfs_palloc_destroy_cache(); callers of the former
function will be added to individual allocators of DAT and ifile on
successive patches.nilfs_palloc_destroy_cache() will be called from nilfs_mdt_destroy()
if the cache is attached to a metadata file. A companion function
nilfs_palloc_clear_cache() is provided to allow releasing buffer head
references independently with the cleanup task. This adjunctive
function will be used before invalidating pages of metadata file with
the cache.Signed-off-by: Ryusuke Konishi

This adds common functions to allocate or deallocate entries with bitmaps
on a meta data file. This feature is used by the DAT and ifile.Signed-off-by: Koji Sato
