I'd like to use printk_ratelimit() in atomic context, but that's not possible right now due to the spinlock usage this commit introduced more than a year ago: 717115e1: printk ratelimiting rewrite As a first step push the lock into the ratelimit state structure. This allows us to deal with locking failures to be considered as an event related to that state being too busy. Also clean up the code a bit (without changing functionality): - tidy up the definitions - clean up the code flow This also shrinks the code a tiny bit: text data bss dec hex filename 264 0 4 268 10c ratelimit.o.before 255 0 0 255 ff ratelimit.o.after ( Whole-kernel data size got a bit larger, because we have two ratelimit-state data structures right now. ) Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: David S.

All ratelimit user use same jiffies and burst params, so some messages (callbacks) will be lost. For example: a call printk_ratelimit(5 * HZ, 1) b call printk_ratelimit(5 * HZ, 1) before the 5*HZ timeout of a, then b will will be supressed. - rewrite __ratelimit, and use a ratelimit_state as parameter. Thanks for hints from andrew. - Add WARN_ON_RATELIMIT, update rcupreempt.h - remove __printk_ratelimit - use __ratelimit in net_ratelimit Signed-off-by: NDave Young <hidave.darkstar@gmail.com> Cc: "David S.

Due to the rcupreempt.h WARN_ON trigged, I got 2G syslog file. For some serious complaining of kernel, we need repeat the warnings, so here I isolate the ratelimit part of printk.c to a standalone file.
