rds: Make rds_sock_lock BH rather than IRQ safe.

2012-01-24T22:03:44+00:00

rds_sock_info() triggers locking warnings because we try to perform a
local_bh_enable() (via sock_i_ino()) while hardware interrupts are
disabled (via taking rds_sock_lock).

There is no reason for rds_sock_lock to be a hardware IRQ disabling
lock, none of these access paths run in hardware interrupt context.

Therefore making it a BH disabling lock is safe and sufficient to
fix this bug.

RDS/IB: print string constants in more places

2010-09-09T01:16:50+00:00

This prints the constant identifier for work completion status and rdma
cm event types, like we already do for IB event types.

A core string array helper is added that each string type uses.

RDS: have sockets get transport module references

2010-09-09T01:16:47+00:00

Right now there's nothing to stop the various paths that use
rs->rs_transport from racing with rmmod and executing freed transport
code.  The simple fix is to have binding to a transport also hold a
reference to the transport's module, removing this class of races.

We already had an unused t_owner field which was set for the modular
transports and which wasn't set for the built-in loop transport.

RDS: remove init and exit annotation

2010-09-09T01:16:39+00:00

The trivial amount of memory saved isn't worth the cost of dealing with section
mismatches.

rds: Use RCU for the bind lookup searches

2010-09-09T01:15:08+00:00

The RDS bind lookups are somewhat expensive in terms of CPU
time and locking overhead.  This commit changes them into a
faster RCU based hash tree instead of the rbtrees they were using
before.

On large NUMA systems it is a significant improvement.

RDS: fold rdma.h into rds.h

2010-09-09T01:11:37+00:00

RDMA is now an intrinsic part of RDS, so it's easier to just have
a single header.

RDS: cleanup: remove "== NULL"s and "!= NULL"s in ptr comparisons

2010-09-09T01:11:32+00:00

Favor "if (foo)" style over "if (foo != NULL)".

net: sk_sleep() helper

2010-04-20T23:37:13+00:00

Define a new function to return the waitqueue of a "struct sock".

static inline wait_queue_head_t *sk_sleep(struct sock *sk)
{
	return sk->sk_sleep;
}

Change all read occurrences of sk_sleep by a call to this function.

Needed for a future RCU conversion. sk_sleep wont be a field directly
available.
