2015-08-29RDMA/amso1100: Deprecate the amso1100 driver and move to stagingSteve Wise1-219/+0
The HW hasn't been sold since 2005, and the SW has definite bit rot. Its time to remove it. So move it to staging for a few releases and then remove it after that. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2014-01-23RDMA/amso1100: Add check if cache memory was allocated before freeing itSvetlana Mavrina1-1/+2
There is a path in handle_vq() where kmem_cache_free() can be called with pointer to a local variable. It can happen if vq_repbuf_alloc() failed to allocate memory from cache and req is NULL. The patch adds check if cache memory was allocated before freeing it. Found by Linux Driver Verification project (linuxtesting.org).

2008-04-17RDMA/amso1100: Add check for NULL reply_msg in c2_intr()Tom Tucker1-1/+5
Fix a place where we might dereference a NULL pointer; this fixes Coverity CID 1392. On inspection I also found a place where we could attempt to kmem_cache_free() a NULL pointer, so fix this too. Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
