- sane dentry retention. Namely, we don't kill /proc/<pid> dentries at the first opportunity (as the current tree does). Instead we do the following: * ->d_delete() kills it only if process is already dead. * all ->lookup() in proc/base.c end with checking if process is still alive and unhash if it isn't. * proc_pid_lookup() (lookup for /proc/<pid>) caches reference to dentry in task_struct. It's _not_ counted in ->d_count. * ->d_iput() resets said reference to NULL. * release_task() (burying a zombie) checks if there is a cached reference and if there is - shrinks the subtree. * tasklist_lock is used for exclusion. That way we are guaranteed that after release_task() all dentries in /proc/<pid> will go away as soon as possible; OTOH, before release_task() we have normal retention policy - they go away under memory pressure with the same rules as for dentries on any other fs.

says it should do - lock out preemption.

This simple check was first suggested by Andrew Morton. Pretty basic - whines if a task exits with a nonzero preempt_count value. I put an identical check in the 2.4 preempt-kernel patch and - sure enough - it was found that XFS essentially disables preemption as it destroys data structures containing locks without first unlocking. The SGI folks are working on that. Anyhow, its a quick and clean solution to debugging potential problems. Patch is against 2.5.7, please apply. Robert Love

Push BKL down to the (few) routines that actually need it, remove it from the do_exit() path.

This patch actually fixes the starvation bug in sys_wait4() by moving any process which is serviced for stoppage to the end of the child list.

David Howells authored
This patch (#1) just converts the task_struct to use struct list_head rather than direct pointers for maintaining the children list.

I removed all the sched.h dependencies and this reduced the size of the patch greatly. I now use current_thread_info() and none of the header or include hackery from before. I've tested this with and without preemption enabled with success. I appreciate your help with this. Again, this is a minimal i386-only patch. I have other arches, documentation, etc. Patch against 2.5.4-pre5. Enjoy, Robert Love

syscall latency improvement * There's now an asm/thread_info.h header file with the basic structure def and asm offsets in it. * There's now a linux/thread_info.h header file which includes the asm version and wraps some bitops calls to make convenience functions for accessing the low-level flags. * The task_struct has had some fields removed (and some flags), and has acquired a pointer to the thread_info struct. * task_struct's are now allocated on slabs in kernel/fork.c, whereas thread_info structs are allocated at the bottom of the stack pages. * Some more convenience functions are provided at the end of linux/sched.h to access flags in other tasks (these are here because they need to access the task_struct).
