nfsd: fail module init on reply cache init failure
If the reply cache initialization fails due to a kmalloc failure, currently we try to soldier on with a reduced (or nonexistant) reply cache. Better to just fail immediately: the failure is then much easier to understand and debug, and it could save us complexity in some later code. (But actually, it doesn't help currently because the cache is also turned off in some odd failure cases; we should probably find a better way to handle those failure cases some day.) Fix some minor style problems while we're at it, and rename nfsd_cache_init() to remove the need for a comment describing it. Acked-by: NeilBrown <neilb@suse.de> Signed-off-by: J. Bruce Fields <bfields@citi.umich.edu>
