From 4688a066ecf60086ea82f68edb3b036b567d2c08 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 22 Jan 2011 20:05:05 +0100 Subject: adfs: remove the big kernel lock According to Russell King, adfs was written to not require the big kernel lock, and all inode updates are done under adfs_dir_lock. All other metadata in adfs is read-only and does not require locking. The use of the BKL is the result of various pushdowns from the VFS operations.
