nilfs2: fix lockdep warnings during disk space reclamation
During disk space reclamation, nilfs2 still emits the following lockdep warning due to page/folio operations on shadowed page caches that nilfs2 uses to get a snapshot of DAT file in memory:

This gets rid of the function to simplify the interface of metadata file.

mm, page_alloc: rename __GFP_WAIT to __GFP_RECLAIM
__GFP_WAIT was used to signal that the caller was in atomic context and could not sleep. Now it is possible to distinguish between true atomic context and callers that are not willing to sleep. The latter should clear __GFP_DIRECT_RECLAIM so kswapd will still wake. As clearing __GFP_WAIT behaves differently, there is a risk that people will clear the wrong flags. This patch renames __GFP_WAIT to __GFP_RECLAIM to clearly indicate what it does -- setting it allows all reclaim activity, clearing them prevents it.

Before 2.6.37, referring to a nilfs object from inodes needed a conditional judgement, and NILFS_I_NILFS was helpful to simplify it. But now we can simply do it by going through a super block instance like inode->i_sb->s_fs_info.

nilfs2: get rid of nilfs_sb_info structure
This directly uses sb->s_fs_info to keep a nilfs filesystem object and fully removes the intermediate nilfs_sb_info structure. With this change, the hierarchy of on-memory structures of nilfs will be simplified as follows:
Before: super_block -> nilfs_sb_info -> the_nilfs -> cptree --+-> nilfs_root (current file system) +-> nilfs_root (snapshot A) +-> nilfs_root (snapshot B) : -> nilfs_sc_info (log writer structure) After: super_block -> the_nilfs -> cptree --+-> nilfs_root (current file system) +-> nilfs_root (snapshot A) +-> nilfs_root (snapshot B) : -> nilfs_sc_info (log writer structure)
The reason why we didn't design so from the beginning is because the initial shape also differed from the above. The early hierachy was composed of "per-mount-point" super_block -> nilfs_sb_info pairs and a shared nilfs object. On the kernel 2.6.37, it was changed to the current shape in order to unify super block instances into one per device, and this cleanup became applicable as the result.

nilfs2: add routines to redirect access to buffers of DAT file
During garbage collection (GC), DAT file, which converts virtual block number to real block number, may return disk block number that is not yet written to the device.
To avoid access to unwritten blocks, the current implementation stores changes to the caches of GCDAT during GC and atomically commit the changes into the DAT file after they are written to the device.
This patch, instead, adds a function that makes a copy of specified buffer and stores it in nilfs_shadow_map, and a function to get the backup copy as needed (nilfs_mdt_freeze_buffer and nilfs_mdt_get_frozen_buffer respectively).
Before DAT changes block number in an entry block, it makes a copy and redirect access to the buffer so that address conversion function (i.e. nilfs_dat_translate) refers to the old address saved in the copy.
This patch gives requisites for such redirection.

nilfs2: add routines to roll back state of DAT file
This adds optional function to metadata files which makes a copy of bmap, page caches, and b-tree node cache, and rolls back to the copy as needed.
This enhancement is intended to displace gcdat inode that provides a similar function in a different way.
In this patch, nilfs_shadow_map structure is added to store a copy of the foregoing states. nilfs_mdt_setup_shadow_map relates this structure to a metadata file. And, nilfs_mdt_save_to_shadow_map() and nilfs_mdt_restore_from_shadow_map() provides save and restore functions respectively. Finally, nilfs_mdt_clear_shadow_map() clears states of nilfs_shadow_map.
The copy of b-tree node cache and page cache is made by duplicating only dirty pages into corresponding caches in nilfs_shadow_map. Their restoration is done by clearing dirty pages from original caches and by copying dirty pages back from nilfs_shadow_map.

nilfs2: add cache framework for persistent object allocator
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.
