From 1579343a73e32b5886e186e8f3e4db85e420ed3f Mon Sep 17 00:00:00 2001 From: Steven Whitehouse Date: Fri, 6 Nov 2009 11:06:37 +0000 Subject: GFS2: Remove dirent_first() function This function only had one caller left, and that caller only called it for leaf blocks, hence one branch of the "if" was never taken. In addition the call to get_left had already verified the metadata type, so the function can be reduced to a single line of code in its caller.
