MDCACHE: add lru release entries process
If something refs a lot of entries at the same time and above the
high water mark, we have no way to release cache entries below water
level,though it can be released.
By adding this process, every time we can try best to release the number
of entries until entries used below the water level, the max number of
release per time is Entries_Release_Size.

recent subscribe requests
by Kaleb Keithley
Hi,
Several people recently subscribed to the ganesha devel list. Unfortunately
I fat-fingered one of them and accidentally rejected the request. And I
can't find where to undo the request.
If you recently subscribed you may wish to try again. (And I realize that
you have to be subscribed to the list to see this, so it's a bit of a
Catch-22 here; unless you're reading the archive.)
And in the meantime we've decided to make the lists "open" and subscribe
requests will be accepted without moderator approval.

Change in ...nfs-ganesha[next]: EXPORT: Set expire_time_attr for export root.
by Name of user not set (GerritHub)
pradeepthomas(a)gmail.com has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/494233 )
Change subject: EXPORT: Set expire_time_attr for export root.
......................................................................
EXPORT: Set expire_time_attr for export root.
MDCACHE sets expire_time_attr based on either what FSAL returns
or from op_ctx->export_perms. This patch initializes expire_time_attr
in op_ctx->export_perms before calling lookup_path from
init_export_root.

expire_time_attr for root of the export.
by Pradeep Thomas
Hello,
The expire_time_attr is set by mdcache_new_entry() and is copied from either FSAL attrs or
op_ctx->export_perms->expire_time_attr. For root of the export, I see this as zero. I think it
is because the root handle is created through lookup_path() and op_ctx is initialized through
init_root_op_context which doesn't set export_perms.expire_time_attr.
The zero expire_time_attr causes every getattr to go to FSAL. Since getattr is called from
several places, this ends up increasing the path length of the call (for ex: READDIR under
export root).
What is the right fix for this? Initializing in init_root_op_context() OR let FSAL to return a
non-zero value?

Change in ...nfs-ganesha[next]: Stop reaper threads before worker threads when shutting down
by Sriram Patil (GerritHub)
Sriram Patil has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/493905 )
Change subject: Stop reaper threads before worker threads when shutting down
......................................................................
Stop reaper threads before worker threads when shutting down
Worker threads may take time to shutdown because of the inflight
operations. During this time a client state can expire and reaper thread
may delete the client recovery directories before shutdown. This means, the
client will not be able to recover the state after server restart/failover.
Ganesha shutdown sequence is changed to stop reaper threads before worker
threads to avoid unfortunate client state deletion.

TIRPC efficient work thread scheduling
by gaurav gangalwar
Hi,
https://github.com/nfs-ganesha/ntirpc/pull/213
I added this fix to try to process more requests with less scheduling.
Scheduling overhead causes big impact in case of low latency workloads.
We got more than 80% benefit for 8k random cached reads with the fix. It has
overall positive impact on other workloads also like random write,
sequential read/write with single and multiple clients.

Change in ...nfs-ganesha[next]: bugfix: initialization ea_entry->e_perm before get permission value

bugfix: initialization ea_entry->e_perm before get permission value
ea_entry was alloc by gsh_malloc which not initialized previously, so the
value in entry->e_perm is uncertain. When we use it with '|' operation,
value of perm may be wrong. We should initialize it first.
