| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | do_smart_update_queue() is called when an operation (semop, semctl(SETVAL), semctl(SETALL), ...) modified the array. It must check which of the sleeping tasks can proceed. do_smart_update_queue() missed a few wakeups: - if a sleeping complex op was completed, then all per-semaphore queues must be scanned - not only those that were modified by *sops - if a sleeping simple op proceeded, then the global queue must be scanned again And: - the test for "|sops == NULL) before scanning the global queue is not required: If the global queue is empty, then it doesn't need to be scanned - regardless of the reason for calling do_smart_update_queue() The patch is not optimized, i.e. even completing a wait-for-zero operation causes a rescan. This is done to keep the patch as simple as possible.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a CB_RECALL the callback service thread flushes the inode using filemap_flush prior to scheduling the state manager thread to return the delegation. When pNFS is used and I/O has not yet gone to the data server servicing the inode, a LAYOUTGET can preceed the I/O. Unlike the async filemap_flush call, the LAYOUTGET must proceed to completion. If the state manager starts to recover data while the inode flush is sending the LAYOUTGET, a deadlock occurs as the callback service thread holds the single callback session slot until the flushing is done which blocks the state manager thread, and the state manager thread has set the session draining bit which puts the inode flush LAYOUTGET RPC to sleep on the forechannel slot table waitq. Separate the draining of the back channel from the draining of the fore channel by moving the NFS4_SESSION_DRAINING bit from session scope into the fore and back slot tables. Drain the back channel first allowing the LAYOUTGET call to proceed (and fail) so the callback service thread frees the callback slot. Then proceed with draining the forechannel.

| | | | | | | | | | | | | | | | | | | | | | | | | | | This seems to have been overlooked when we did the namespace conversion.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to the NFS security flavour negotiation mean that we have a stronger dependency on rpc.gssd. If the latter is not running, because the user failed to start it, then we time out and mark the container as not having an instance. We then use that information to time out faster the next time. If, on the other hand, the rpc.gssd successfully binds to an rpc_pipe, then we mark the container as having an rpc.gssd instance. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

A mutex didn't worked either and brings more overhead by turning off interrupts. So, let's use the fastest path for parisc which is the ldcw instruction. Counting how often the irq stack was used is pretty useless, so just drop this piece of code. Signed-off-by: Helge Deller <deller@gmx.de>

They are currently not reentrant in that they save register context before the stack is set or adjusted. I have observed a number of system crashes where there was clear evidence of stack corruption during interrupt processing, and as a result register corruption. Some interruptions can still occur during interruption processing, however external interrupts are disabled and data TLB misses don't occur for absolute accesses. So, it's not entirely clear what triggers this issue. Also, if an interruption occurs when Q=0, it is generally not possible to recover as the shadowed registers are not copied. The attached patch reworks the get_stack_use_cr30 and get_stack_use_r30 macros to allocate stack before doing register saves. The new code is a couple of instructions shorter than the old implementation. Thus, it's an improvement even if it doesn't fully resolve the stack corruption issue. Based on limited testing, it improves SMP system stability. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de>

| | * | | xfs: fix missing KM_NOFS tags to keep lockdep happyDave Chinner2013-05-244-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several places where we use KM_SLEEP allocation contexts and use the fact that they are called from transaction context to add KM_NOFS where appropriate. Unfortunately, there are several places where the code makes this assumption but can be called from outside transaction context but with filesystem locks held. These places need explicit KM_NOFS annotations to avoid lockdep complaining about reclaim contexts.
