This is a resend of a patchset that I sent last month, reworked to remove some controversial locking proposals. All locking is now explicit. This patchset provides: 1) A new write_string() cgroup file method that copies the user's data to kernel space and invokes the relevant handler with the nul-terminated kernelspace buffer 2) A new helper function, cgroup_lock_live_group(), which combines taking the cgroup lock and checking the liveness of a cgroup, to allow simplification of a common lock/check idiom in cgroup file handlers. 3) Conversion of several raw write handlers in cgroup, cpuset, devcgroup and res_counter to use typed handlers and the new locking specifications.
