I couldn't avoid much of the code duplication, but at least made things incremental. Does somebody now a test suite that exists for the idr API, that I could run on this new api? Mike, can you try to run it on your victim: I had such a hard time building this patch, that I couldn't re-run the test on my 8-core with this new version. So the last results I have are for 2.6.25-rc3-mm1. Also, I think a careful review should be done to avoid introducing yet other problems :-( *WARNING*: this patch contains a fix for idr.c I know, I'm doing things bad, but I only saw the problem this afternoon. It should be applied on linux-2.6.25-rc8-mm1, in the following order: [ PATCH 01/13 ] : copy_idr_code.patch [ PATCH 02/13 ] : change_ridr_struct.patch [ PATCH 03/13 ] : ridr_pre_get.patch [ PATCH 04/13 ] : ridr_alloc_layer.patch [ PATCH 05/13 ] : ridr_free_layer.patch [ PATCH 06/13 ] : ridr_sub_alloc.patch [ PATCH 07/13 ] : ridr_get_empty_slot.patch [ PATCH 08/13 ] : ridr_get_new.patch [ PATCH 09/13 ] : ridr_remove.patch [ PATCH 10/13 ] : ridr_find.patch [ PATCH 11/13 ] : ridr_integrate.patch [ PATCH 12/13 ] : ipc_use_ridr.patch [ PATCH 13/13 ] : remove_ipc_lock_down.patch Regards, Nadia --
