From 01b2d93ca4c495f056471189ac6c4e6ac4cbbccb Mon Sep 17 00:00:00 2001 From: Vadim Lobanov Date: Fri, 22 Dec 2006 01:10:43 -0800 Subject: [PATCH] fdtable: Provide free_fdtable() wrapper Christoph Hellwig has expressed concerns that the recent fdtable changes expose the details of the RCU methodology used to release no-longer-used fdtable structures to the rest of the kernel. The trivial patch below addresses these concerns by introducing the appropriate free_fdtable() calls, which simply wrap the release RCU usage. Since free_fdtable() is a one-liner, it makes sense to promote it to an inline helper.
