[PATCH 0/9] Scalability requirements for sysv ipc - v3
After scalability problems have been detected when using the sysV ipcs, I have proposed to use an RCU based implementation of the IDR api instead (see threads http://lkml.org/lkml/2008/4/11/212 and http://lkml.org/lkml/2008/4/29/295). This resulted in many people asking to convert the idr API and make it rcu s... 7 May 2008 07:28

[PATCH 2/9] Rename some of the idr APIs internal routines
[PATCH 02/09] This is a trivial patch that renames: . alloc_layer to get_from_free_list since it idr_pre_get that actually allocates memory. . free_layer to move_to_free_list since memory is not actually freed there. This makes things more clear for the next patches. Signed-off-by: Nadia Derbey <... 7 May 2008 07:28

[PATCH] IB/ehca: Protect QP against destroying until all async events for it are handled.
This is necessary because, in a multicore environment, a race between uverbs async handler and destroy QP could occur. Signed-off-by: Stefan Roscher <stefan.roscher at de.ibm.com> --- We are not sure if this should be fixed in the driver or in uverbs itself. Roland, what's your opinion about this? drivers/... 7 May 2008 15:04
