The OCFS2 DLM allocates a number of pages for a hash to lookup locks.
There was a bug where a PAGE_SIZE bigger than the hash size (eg, 64K
pages) would result in zero pages allocated.

This allows us to have a hash table greater than a single page which greatly
improves dlm performance on some tests.

Gains us a bit of performance on loads which heavily hit the lockres hash.

The changes in the tty handling contain a bug while accessing

This file was created due to the issue regarding how to notify people
that devfs was going to be removed. Finally remove the entry as it has
served its purpose.

I've always found this flag confusing. Now that devfs is no longer around, it
has been renamed, and the documentation for when this flag should be used has
been updated.
Also fixes all drivers that use this flag.
