modules: only use mod->param_lock if CONFIG_MODULES (2015-06-28 14:50:12 +0930)
----------------------------------------------------------------
Minor merge needed, due to function move.
Main excitement here is Peter Zijlstra's lockless rbtree optimization to
speed module address lookup. He found some abusers of the module lock
doing that too.
A little bit of parameter work here too; including Dan Streetman's breaking
up the big param mutex so writing a parameter can load another module (yeah,
really). Unfortunately that broke the usual suspects, !CONFIG_MODULES and
!CONFIG_SYSFS, so those fixes were appended too.
Cheers,
Rusty.
----------------------------------------------------------------
Dan Streetman (2):
module: make perm const
module: add per-module param_lock
Gobinda Charan Maji (1):
sysfs: tightened sysfs permission checks
Luis R. Rodriguez (6):
kernel/params: constify struct kernel_param_ops uses
kernel/module.c: use generic module param operaters for sig_enforce
kernel/params.c: generalize bool_enable_only
kernel/params.c: export param_ops_bool_enable_only
kernel/workqueue.c: remove ifdefs over wq_power_efficient
kernel/module.c: avoid ifdefs for sig_enforce declaration
Peter Zijlstra (12):
module: Annotate module version magic
module, jump_label: Fix module locking
module: Sanitize RCU usage and locking
rbtree: Make lockless searches non-fatal
seqlock: Better document raw_write_seqcount_latch()
rcu: Move lockless_dereference() out of rcupdate.h
seqlock: Introduce raw_read_seqcount_latch()
rbtree: Implement generic latch_tree
module: Optimize __module_address() using a latched RB-tree
module: Make the mod_tree stuff conditional on PERF_EVENTS || TRACING
module: Use __module_address() for module_address_lookup()
module: Rework module_addr_{min,max}
Rusty Russell (3):
modules: clarify CONFIG_MODULE_COMPRESS help, suggest 'N'.
params: suppress unused variable error, warn once just in case code changes.
param: fix module param locks when !CONFIG_SYSFS.
Stephen Rothwell (2):
rcu: merge fix for Convert ACCESS_ONCE() to READ_ONCE() and WRITE_ONCE()
modules: only use mod->param_lock if CONFIG_MODULES
