Since we forgot to set the cache's nextcheck value, that could take up to 30 minutes. Also, though there's probably no real bug in this case, setting CACHE_NEGATIVE directly like this probably isn't a great idea in general. So let's just remove the entry from the cache directly, and move this bit of cache manipulation to a helper function.

Pointer arithmetic is considered more portable, and is used throughout the kernel's existing XDR encoders. The gcc optimizer generates similar assembler code either way. Byte-swapping before a memory store on x86 typically results in an instruction pipeline stall. Avoid byte-swapping when encoding a new header. svcrdma currently doesn't alter a connection's credit grant value after the connection has been accepted, so it is effectively a constant. Cache the byte-swapped value in a separate field. Christoph suggested pulling the header encoding logic into the only function that uses it.

A new startup of nfsd, rpc.mountd, etc, 2. A rpc request from client (pynfs test, or normal mounting), 3. An ip_map cache is created but invalid, so upcall to rpc.mountd, 4. rpc.mountd process the ip_map upcall, before write the valid data to nfsd, do auth_reload(), and check_useipaddr(), 5. For the first time, old_use_ipaddr = -1, it causes rpc.mountd do write_flush that doing cache_clean, 6. The ip_map cache will be treat as expired and clean, 7. When rpc.mountd write the valid data to nfsd, a new ip_map is created and updated, the cache_check of old ip_map(doing the upcall) will return -ETIMEDOUT. 8. RPC layer return SVC_CLOSE and close the xprt after commit 4d712ef1db05 "svcauth_gss: Close connection when dropping an incoming message" NeilBrown suggest in another email, "If CACHE_VALID is not set, then there is no data in the cache item, so there is nothing to expire. So it would be nice if cache items that don't have CACHE_VALID are never treated as expired." v3, change the order of the two patches v2, change the checking of CACHE_PENDING to CACHE_VALID Reviewed-by: NeilBrown Signed-off-by: Kinglong Mee Signed-off-by: J.
