* Make /proc/misc use seq_list_xxx helpersPavel Emelianov2007-07-16
| | | | | | | | Simple and stupid - just use the helpers. Signed-off-by: Pavel Emelianov <xemul@openvz.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* use mutex instead of semaphore for misc char devicesMatthias Kaehlcke2007-05-08
| | | | | | | | | The misc character device driver uses a semaphore as mutex. Use the mutex API instead of the (binary) semaphore.

* [PATCH] Correct misc_register return code handling in several driversNeil Horman2006-12-07
| | | | | | | | | | | | | | | | | | | | | | | | | Clean up several code points in which the return code from misc_register is not handled properly. Several modules failed to deregister various hooks when misc_register fails, and this patch cleans them up. Also there are a few modules that legitimately don't care about the failure status of misc register. These drivers however unilaterally call misc_deregister on module unload. Since misc_register doesn't initialize the list_head in the init_routine if it fails, the deregister operation is at risk for oopsing when list_del is called. The initial solution was to manually init the list in the miscdev structure in each of those modules, but the consensus in this thread was to consolodate and do that universally inside misc_register.

* Driver core: change misc class_devices to be real devicesGreg Kroah-Hartman2006-12-01
| | | | | | | | This also ment that some of the misc drivers had to also be fixed up as they were assuming the device was a class_device. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] make more file_operation structs staticArjan van de Ven2006-07-03
| | | | | | | | | | | | Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

| | | | | | | | | | | | This patch removes CONFIG_PMAC_PBOOK (PowerBook support). This is now split into CONFIG_PMAC_MEDIABAY for the actual hotswap bay that some powerbooks have, CONFIG_PM for power management related code, and just left out of any CONFIG_* option for some generally useful stuff that can be used on non-laptops as well.

* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-16
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
