2009-06-24tty: fix tty_port_block_til_ready waitingJiri Slaby1-1/+1
Since commit 3e3b5c087799e536871c8261b05bc28e4783c8da ("tty: use prepare/finish_wait"), tty_port_block_til_ready() is using prepare_to_wait()/finish_wait(). Those functions require that the wait_queue_t be initialised with .func=autoremove_wake_function, via DEFINE_WAIT(). But the conversion from DECLARE_WAITQUEUE() to DEFINE_WAIT() was not made, so this code will oops in finish_wait().

2009-06-24reiserfs: minimal fix for ACL cachingAl Viro1-1/+1
reiserfs uses NULL as "unknown" and ERR_PTR(-ENODATA) as "no ACL"; several codepaths store the former instead of the latter. All those codepaths go through iset_acl() and all cases when it's called with NULL acl are for the second variety, so the minimal fix is to teach iset_acl() to deal with that. Proper fix is to switch to more usual conventions and avoid back and forth between internally used ERR_PTR(-ENODATA) and NULL expected by the rest of the kernel.

There is no reason to for the split between __writeback_single_inode and __sync_single_inode, the former just does a couple of checks before tail-calling the latter. So merge the two, and while we're at it split out the I_SYNC waiting case for data integrity writers, as it's logically separate function.

2009-06-24Make allocation of anon devices cheaperAl Viro1-1/+6
Standard trick - add a new variable (start) such that for each n < start n is known to be busy. Allocation can skip checking everything in [0..start) and if it returns n, we can set start to n + 1. Freeing below start sets start to what we'd just freed. Of course, it still sucks if we do something like free 0 allocate allocate in a loop - still O(n^2) time. However, on saner loads it improves the things a lot and the entire thing is not worth the trouble of switching to something with better worst-case behaviour.

2009-06-24timer stats: Optimize by adding quick check to avoid function callsHeiko Carstens4-8/+19
When the kernel is configured with CONFIG_TIMER_STATS but timer stats are runtime disabled we still get calls to __timer_stats_timer_set_start_info which initializes some fields in the corresponding struct timer_list. So add some quick checks in the the timer stats setup functions to avoid function calls to __timer_stats_timer_set_start_info when timer stats are disabled. In an artificial workload that does nothing but playing ping pong with a single tcp packet via loopback this decreases cpu consumption by 1 - 1.5%.

It's rather confusing that in t_start(), in some cases @pos is incremented, and in some cases it's decremented and then incremented. This patch rewrites t_start() in a much more general way.

The output size of available_events is < 4 pages, which means we lost 1 entry per page. The cause is, it's wrong to increment @pos in s_start(). Actually there's another bug here -- reading avaiable_events/set_events can race with module unload: # cat available_events | s_start() | s_stop() | | # rmmod foo.ko s_start() | call = list_entry(m->private) | @call might be freed and accessing it will lead to crash.
