Rick Macklem 96b40b8967 nfscl: Use hash lists to improve expected search performance for opens ... A problem was reported via email, where a large (130000+) accumulation of NFSv4 opens on an NFSv4 mount caused significant lock contention on the mutex used to protect the client mount's open/lock state. Although the root cause for the accumulation of opens was not resolved, it is obvious that the NFSv4 client is not designed to handle 100000+ opens efficiently. When searching for an open, usually for a match by file handle, a linear search of all opens is done. Commit 3f7e14ad93 added a hash table of lists hashed on file handle for the opens. This patch uses the hash lists for searching for a matching open based of file handle instead of an exhaustive linear search of all opens. This change appears to be performance neutral for a small number of opens, but should improve expected performance for a large number of opens. This commit should not affect the high level semantics of open handling. MFC after: 2 weeks		2021-05-27 19:08:36 -07:00
