Update of /home/cvs/mtd/drivers/mtd/devices
In directory phoenix.infradead.org:/tmp/cvs-serv3026

Modified Files:
	blkmtd.c 
Log Message:

- remove outgoing write queue and kernel thread. Replace with a kiobuf
  which is filled on writes and written out when full or a write to an
  earlier block is made.

- treat erases like writes and remove the 'erase_page' which was
  incorrectly used anyway as all entries in a kiobuf cannot point to
  the same page.

- replace readpage() with read_pages() which reads in a list of
  required pages.

- Add a kiobuf into the struct blkmtd_dev for reading and only allocate
  another if this one is in use. This is protected by the iobuf_locks.

- blkmtd_write(), blkmtd_erase() now call write_pages() do write the
  data into the pages in the cache.

- commit_pages() added to write the dirty pages to disk.

- add 'sync' option to force all writes to be synchronous.
