The console drivers are called while the console_may_schedule flag is still true. The might_sleep() is triggered when fbcon calls console_conditional_schedule(). Fix by setting console_may_schedule to zero earlier, before the call to the console drivers. Signed-off-by:

ufs_get_locked_page is called twice in ufs code, one time in ufs_truncate path(we allocated last block), and another time when fragments are reallocated. In ideal world in the second case on allocation/free block layer we should not know that things like `truncate' exists, but now with such crutch like ufs_get_locked_page we can (or should?) skip truncated pages.

As discussed earlier: http://lkml.org/lkml/2006/6/28/136 this patch fixes such issue: `ufs_get_locked_page' takes page from cache after that `vmtruncate' takes page and deletes it from cache `ufs_get_locked_page' locks page, and reports about EIO error. Also because of find_lock_page always return valid page or NULL, we have no need to check it if page not NULL. Signed-off-by:

The retry logic of unqueue_me only works if we can guarantee, that the original value of q->lock_ptr is always a spinlock (Otherwise we overwrite kernel memory). We know that q->lock_ptr can change. I dont know what happens with the original spinlock, as I am not an expert with the futex code. Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Rusty Russell <rusty@rustcorp.com.au> Acked-by:

It should be possible to suspend, either to RAM or to disk, if there's a traced process that has just reached a breakpoint. However, this is a special case, because its parent process might have been frozen already and then we are unable to deliver the "freeze" signal to the traced process. If this happens, it's better to cancel the freezing of the traced process. Ref. http://bugzilla.kernel.org/show_bug.cgi?id=6787 Signed-off-by:

-
Dean Nelson authored
The uncached allocator has a function, uncached_get_new_chunk(), that needs to be serialized on a per node basis. It also has a global variable, allocated_granules, which should be defined on a per node basis and protected by that serialization. Additionally, all error returns from functions called (like ia64_pal_mc_drain()) should be handled appropriately. Signed-off-by:
