From 9e4c6379a62d94d3362b12c7a00f2105df6d7eeb Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Wed, 9 Sep 2009 16:32:54 +1000 Subject: [PATCH] sunrpc/cache: change cache_defer_req to return -ve error, not boolean. As "cache_defer_req" does not sound like a predicate, having it return a boolean value can be confusing. It is more consistent to return 0 for success and negative for error. Exactly what error code to return is not important as we don't differentiate between reasons why the request wasn't deferred, we only care about whether it was deferred or not.
