From b93f858ab2a4bee779c360002f313ad6c3504cdc Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Wed, 26 Nov 2008 12:03:55 +0100 Subject: [PATCH] fuse: add fuse_ prefix to several functions Add fuse_ prefix to request_send*() and get_root_inode() as some of those functions will be exported for CUSE. With or without CUSE export, having the function names scoped is a good idea for debuggability.
