drivers/block/aoe/aoeblk.c: ratelimit a warning printk
As described in https://bugzilla.kernel.org/show_bug.cgi?id=19922 : I had an AoE device go down overnight, and while a server was trying to : write to it, it was also writing this message to its logs: : : 209 printk(KERN_INFO "aoe: device %ld.%d is not up\n", : 210 d->aoemajor, d->aoeminor); : : The message appeared many times per second, and over several hours : produced about 7.5 gigabytes of log files, filling up all free space on : the root filesystem.
