The demote_ok glock operation is only still used to prevent the inode
glocks of the "jindex" and "rindex" directories from getting recycled
while they are still referenced by sdp->sd_jindex and sdp->sd_rindex.
However, the LRU walking code will no longer recycle glocks which are
referenced, so the demote_ok glock operation is obsolete and can be
removed.
Each of a glock's holders in the gl_holders list is holding a reference
on the glock, so when the list of holders isn't empty in demote_ok(),
the existing reference count check will already prevent the glock from
getting released. This means that demote_ok() is obsolete as well.

Rearrange the table of locking modes and associated caching capability
to be in order of increasing caching capability.
Update the description of the glock operations.

- Fix a glock state (non-)transition bug when a dlm request times out
and is canceled, and we have locking requests that can now be granted
immediately.
- Various fixes and cleanups in how the logd and quotad daemons are
woken up and terminated.
- Fix several bugs in the quota data reference counting and shrinking.
Free quota data objects synchronously in put_super() instead of
letting call_rcu() run wild.
- Make sure not to deallocate quota data during a withdraw; rather, defer
quota data deallocation to put_super(). Withdraws can happen in
contexts in which callers on the stack are holding quota data references.
- Many minor quota fixes and cleanups by Bob.
- Update the the mailing list address for gfs2 and dlm. (It's the same
list for both and we are moving it to gfs2@lists.linux.dev.)
- Various other minor cleanups.
