Mike Marciniszyn	4db62d4786	IB/qib: Fix refcount leak in lkey/rkey validation ... The mr optimization introduced a reference count leak on an exception test. The lock/refcount manipulation is moved down and the problematic exception test now calls bail to insure that the lock is released. Additional fixes as suggested by Ralph Campbell <ralph.campbell@qlogic.org>: - reduce lock scope of dma regions - use explicit values on returns vs. automatic ret value Signed-off-by: Mike Marciniszyn <mike.marciniszyn@qlogic.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>	2011-01-10 17:42:23 -08:00
Mike Marciniszyn	2a600f14d2	IB/qib: RDMA lkey/rkey validation is inefficient for large MRs ... The current code loops during rkey/lkey validiation to isolate the MR for the RDMA, which is expensive when the current operation is inside a very large memory region. This fix optimizes rkey/lkey validation routines for user memory regions and fast memory regions. The MR entry can be isolated by shifts/mods instead of looping. The existing loop is preserved for phys memory regions for now.
