Here is a list of things reiser4 needs from the core:

(1) export of generic_forget_inode()

(2) export of page_cache_readahead()

(3) export of remove_from_page_cache()

(4) export of fsync_super()

(5) patch to allow safe sharing of ->journal_info pointer in task_struct
by several users

(1)-(4) are only necessary to compile reiser4 as module.

(5) is good not only for reiser4. Without it different file systems
using ->journal_info cannot "co-exist peacefully".

No new system calls are introduced (yet).

Nikita.
