From 12062dddda450976b129dcb1bacd91acaf4d8030 Mon Sep 17 00:00:00 2001 From: Eric Sandeen Date: Mon, 15 Feb 2010 14:19:27 -0500 Subject: ext4: move __func__ into a macro for ext4_warning, ext4_error Just a pet peeve of mine; we had a mishash of calls with either __func__ or "function_name" and the latter tends to get out of sync. I think it's easier to just hide the __func__ in a macro, and it'll be consistent from then on.
