The "broken in pipe" handler of the USB-HDM calls most_stop_enqueue() to stop the MBO traffic before returning all MBOs back to the Mostcore. As the enqueue() call from the Mostcore may run in parallel with the most_stop_enqueue(), the HDM may run into the inconsistent state and crash the kernel. This patch synchronizes enqueue(), most_stop_enqueue() and most_resume_enqueue() with a mutex, hence avoiding the race condition. Signed-off-by:

This patch is needed to ensure that submitted URBs get unlinked before the driver calls usb_clear_halt(). Since the halt condition of an USB endpoint is channel related, the work_struct is moved from a buffer basis to a channel basis. Signed-off-by:

Currently, the aim-cdev is returning different error codes for the same root cause. This patch is needed to get rid of the module's inconsistency when reporting errors. Signed-off-by:

Remove the lmm and lmmsize parameters from both functions, storing that data in md_op_data when needed. Remove the unused lookup_flags parameter from md_intent_lock(), and the unused reqp parameter from md_enqueue(). Add a union ldlm_policy_data * parameter to md_enqueue(). Remove the unused function lmv_enqueue_remote(). Signed-off-by:

Move directory entries cache from llite to MDC, so client side dir stripe will use independent hash function(in LMV), which does not need to be tightly coupled with the backend storage dir-entry hash function. With striped directory, it will be 2-tier hash, LMV calculate hash value according to the name and hash-type in layout, then each MDT will store these entry in disk by its own hash. Signed-off-by:

if the name already exists, but we don't have write permissions in the parent, force talking to the MDS to determine what more sensical error code to return. This also happens to fix matlab and other such programs that assume that EEXIST is the only valid error code for mkdir of an existing directory. Signed-off-by:

In current code, when a CON RACE occurs, the passive side will let the node with the higher NID value win the race. We have a field case where a node can have a "stuck" connection which never goes away and is the trigger of a never-ending loop of re-connections. This patch introduces a counter to how many times a connection in a connecting state has been the cause of a CON RACE rejection. After 20 times (constant MAX_CONN_RACES_BEFORE_ABORT), we assume the connection is stuck and let the other side (with lower NID) win. Signed-off-by:

kiblnd_check_sends() takes conn::ibc_lock at the begin and release this lock at the end, this is inefficient because most use-case needs to explicitly release ibc_lock before caling this function. This patches changes it to kiblnd_check_sends_locked() and avoid unnecessary lock dances. Signed-off-by:

IB network may lose last connection handshake packet. This problem isn't Lustre specific and described at https://oss.oracle.com/pipermail/rds-devel/2007-December/000271.html for example. Solution is to make conection established if any packet is received for it. Signed-off-by:

There is a case in lnet_parse() where we discover that LNet is shutting down but we continue to use the NI when we drop the message and end up calling ko2iblnd_check_send_locked() which tries to allocate from the Tx pool which has been cleaned up already. This triggers a NULL pointer dereference. This fix just returns from lnet_parse() when we disover LNet is shutting down. Signed-off-by:
