sunrpc: increase MAX_HASHTABLE_BITS to 14

2010-09-12T23:55:26Z

The maximum size of the authcache is now set to 1024 (10 bits), but on our server we need at least 4096 (12 bits). Increase MAX_HASHTABLE_BITS to 14. This is a maximum of 16384 entries, each containing a pointer (8 bytes on x86_64). This is exactly the limit of kmalloc() (128K). Signed-off-by: Miquel van Smoorenburg Signed-off-by: Trond Myklebust

SUNRPC: Move the bound cred to struct rpc_rqst

2010-08-04T12:54:09Z

This will allow us to save the original generic cred in rpc_message, so that if we migrate from one server to another, we can generate a new bound cred without having to punt back to the NFS layer. Signed-off-by: Trond Myklebust

SUNRPC: Make the credential cache hashtable size configurable

2010-08-04T12:54:06Z

This patch allows the user to configure the credential cache hashtable size using a new module parameter: auth_hashtable_size When set, this parameter will be rounded up to the nearest power of two, with a maximum allowed value of 1024 elements. Signed-off-by: Trond Myklebust

SUNRPC: Store the hashtable size in struct rpc_cred_cache

2010-08-04T12:54:05Z

Cleanup in preparation for allowing the user to determine the maximum hash table size. Signed-off-by: Trond Myklebust
