The main changes are:\n . This ipc_ids structure is changed: the entries array is changed into a\n root idr structure.\n . The grow_ary() routine is removed: it is not needed anymore when adding\n an ipc structure, since we are now using the IDR facility.\n . The ipc_rmid() routine interface is changed:\n . there is no need for this routine to return the pointer passed in as\n argument: it is now declared as a void\n . since the id is now part of the kern_ipc_perm structure, no need to\n have it as an argument to the routine\n\nSigned-off-by: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "d2b20b11547cefc89d6c81937e81afaf3c62808b", "tree": "50a6c8e1d86c38fff417907d821eec0e0731e1a5", "parents": [ "73e753a50dcac7d6d4fa8b9552203ef544a70d77" ], "author": { "name": "Gautham R Shenoy", "email": "ego@in.ibm.com", "time": "Thu Oct 18 23:40:47 2007 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Fri Oct 19 11:53:44 2007 -0700" }, "message": "Add irq protection in the percpu-counters cpu-hotplug-callback path\n\nSome of the per-cpu counters and thus their locks are accessed from IRQ\ncontexts.
