Fix missing of last user while dumping slab corruption log
TAO HU kirjoitti: Actually we greped "kmem_cache_create" in whole kernel souce tree (2.6.29 and 2.6.32). Either "align" equal to "0" or flag SLAB_HWCACHE_ALIGN is used when calling kmem_cache_create(). I don't think that's correct. The "task_xstate" has alignof(struct task_xstate) and there seems t... 13 Apr 2010 06:10
xtables: make XT_ALIGN() usable in exported headers by exporting __ALIGN_KERNEL()
Alexey Dobriyan wrote: XT_ALIGN() was rewritten through ALIGN() by commit 42107f5009da223daa800d6da6904d77297ae829 "netfilter: xtables: symmetric COMPAT_XT_ALIGN definition". ALIGN() is not exported in userspace headers, which created compile problem for tc(8) and will create problem for iptables(8). ... 13 Apr 2010 06:11
SO_REUSEADDR with UDP (again)
Hello, I found SO_REUSEADDR on UDP sockets to behave somewhat nasty. If you create a UDP socket with that flag and bind it to a port, then anyone doing the same later will "steal" your packets, ie. 1. process A binds to port 12345 with SO_REUSEADDR, packets to that port go to process A 2. process B binds t... 13 Apr 2010 06:10
DMA Engine API usage
Hello Dan, I have some doubts regarding DMA API usage on its clients for example MMC, ALSA, USB etc. I am going to take example of the ALSA framework. Audio data transfer is initiated in soc_pcm_trigger(). This is called in an atomic context, with spinlock held and irqs disabled. Here most drivers enable data ... 13 Apr 2010 05:05
Best way to do kernel only ldisc without user-space ldisc attaching?
Hello, I have a line discpline driver for a custom protocol over an UART. This driver implements the following callbacks: open/close, receive_buf/write_wakeup. So far, I have an ugly hack, which opens the /dev/tty<N> in the kernel, and directly uses the f_op and unlocked_ioctl functions to do the ldisc number... 13 Apr 2010 05:05
perf: Move arch specific code into separate arch directory
Hi Masami, Thanks for the feedback Excerpts from Masami Hiramatsu's message of Mon Apr 12 22:37:03 +1000 2010: Could you add a check whether the get_arch_regstr() is defined (or dwarf-regs.h is exist) in Makefile?
