Change in ...nfs-ganesha[next]: MDCACHE - Cancel dirmap LRU when destroying export
by Daniel Gryniewicz (GerritHub)
Daniel Gryniewicz has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/460866 )
Change subject: MDCACHE - Cancel dirmap LRU when destroying export
......................................................................
MDCACHE - Cancel dirmap LRU when destroying export
The dirmap LRU thread accesses the export, but when the export is
removed, this causes a use-after-free. Cancel the dirmap LRU when it's
export is removed.

Change in ...nfs-ganesha[next]: Do not show queue latencies in ganesha_stats
by Sachin Punadikar (GerritHub)
Sachin Punadikar has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/460834 )
Change subject: Do not show queue latencies in ganesha_stats
......................................................................
Do not show queue latencies in ganesha_stats
With latest Ganesha, there are no RPC queues maintained. In that context
there is no meaning of fetching and displaying queue latencies.

Release memory allocated to callback client
For every async request being sent for NLM protocol, CLIENT structure

2.7.4 core in mdcache (includes the patches)
by Rungta, Vandana
Daniel,
Core in mdcache when mdcache_lru_unref_chunk. Ref count is 0.
I started these tests 10 days ago with all the mdcache patches including the one moving the unref_chunk in readdir_chunked to inside the lock. The test continues to readdir over 5 million entries while writing/reading/deleting content. I have 2 test setups – both using a Windows client that hit this core.
Let me know if there is additional information you need from the cores.
Thanks,
Vandana
