*	ipc/sem.c: rewrite undo list locking	Manfred Spraul	2008-07-25	1	-1/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	The attached patch: - reverses the locking order of ulp->lock and sem_lock: Previously, it was first ulp->lock, then inside sem_lock. Now it's the other way around. - converts the undo structure to rcu. Benefits: - With the old locking order, IPC_RMID could not kfree the undo structures. The stale entries remained in the linked lists and were released later. - The patch fixes a a race in semtimedop(): if both IPC_RMID and a semget() that recreates exactly the same id happen between find_alloc_undo() and sem_lock, then semtimedop() would access already kfree'd memory.

*	ipc/sem.c: convert undo structures to struct list_head	Manfred Spraul	2008-07-25	1	-6/+6
\| \| \| \| \| \| \| \| \| \| \| \|	The undo structures contain two linked lists, the attached patch replaces them with generic struct list_head lists.

*	ipc: store ipcs into IDRs	Nadia Derbey	2007-10-19	1	-1/+0
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch introduces ipcs storage into IDRs. The main changes are: . This ipc_ids structure is changed: the entries array is changed into a root idr structure. . The grow_ary() routine is removed: it is not needed anymore when adding an ipc structure, since we are now using the IDR facility. . The ipc_rmid() routine interface is changed: . there is no need for this routine to return the pointer passed in as argument: it is now declared as a void . since the id is now part of the kern_ipc_perm structure, no need to have it as an argument to the routine Signed-off-by: Nadia Derbey <Nadia.Derbey@bull.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

*	[PATCH] fix remaining missing includes	Tim Schmielau	2005-11-07	1	-0/+2
\| \| \| \| \| \| \| \| \| \|	Fix more include file problems that surfaced since I submitted the previous fix-missing-includes.patch. This should now allow not to include sched.h from module.h, which is done by a followup patch.

*	Linux-2.6.12-rc2v2.6.12-rc2	Linus Torvalds	2005-04-16	1	-0/+157
	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!
