From df95a9d4fb91d819d3fb55dd437056df59e7f15e Mon Sep 17 00:00:00 2001 From: "J. Bruce Fields" Date: Thu, 8 Nov 2007 16:09:59 -0500 Subject: knfsd: cache unregistration needn't return error There's really nothing much the caller can do if cache unregistration fails. And indeed, all any caller does in this case is print an error and continue. So just return void and move the printk's inside cache_unregister. Acked-by: NeilBrown Signed-off-by: J.
