[PATCH] dcache changes for preparing for "export_operations" interface for nfsd to use.
Prepare for new export_operations interface (for filehandle lookup):
- define d_splice_alias and d_alloc_anon.
- define shrink_dcache_anon for removing anonymous dentries
- modify d_move to work with anonymous dentries (IS_ROOT dentries)
- modify d_find_alias to avoid anonymous dentries where possible
as d_splice_alias and d_alloc_anon use this
- put in place infrastructure for s_anon allocation and cleaning
- replace a piece of code that is in nfsfh, reiserfs and fat
with a call to d_alloc_anon
- Rename DCACHE_NFSD_DISCONNECTED to DCACHE_DISCONNECTED
- Add documentation at Documentation/filesystems/Exporting
