From a5f37c3252b174efdcdd808797a7c529064c95c0 Mon Sep 17 00:00:00 2001 From: Sven Schnelle <svens@stackframe.org> Date: Wed, 2 Apr 2008 13:17:18 +0100 Subject: afs: add missing up_write() on return If afs_cell_alloc() fails, afs_cells_sem doesn't get unlocked, which leads to a deadlock. Unlock it before returning.
