rcutorture: Remove redundant assignment to cur_ops in for loop

2007-05-08T18:15:17+00:00

The for loop in rcutorture_init uses the condition
cur_ops = torture_ops[i], cur_ops
but then makes the same assignment to cur_ops inside the loop.  Remove the
redundant assignment inside the loop, and remove now-unnecessary braces.

rcutorture: Mark rcu_torture_init as __init

2007-05-08T18:15:00+00:00

The corresponding rcu_torture_cleanup cannot get marked as __exit, because
rcu_torture_init uses it to clean up if init fails.

[PATCH] Publish rcutorture module parameters via sysfs, read-only

2007-03-06T17:30:25+00:00

rcutorture's module parameters currently use permissions of 0, so they
don't show up in /sys/module/rcutorture/parameters.  Change the permissions
on all module parameters to world-readable (0444).

rcutorture does all of its initialization and thread startup when loaded
and relies on the parameters not changing during execution, so they should
not permit writing.  However, reading seems fine.

[PATCH] Add Sparse annotations to SRCU wrapper functions in rcutorture

2006-12-07T16:39:44+00:00

The SRCU wrapper functions srcu_torture_read_lock and
srcu_torture_read_unlock in rcutorture intentionally change the SRCU
context; annotate them accordingly, to avoid a warning.

Use the newly-generic synchronous deferred free function to implement torture
testing for rcu_bh using synchronize_rcu_bh rather than the asynchronous
call_rcu_bh.
