[PATCH] CIFS: Fix SMB2 oplock break processing

by Pavel Shilovsky

Even when mounting modern protocol version the server may be configured without supporting SMB2.1 leases and the client uses SMB2 oplock to optimize IO performance through local caching. However there is a problem in oplock break handling that leads to missing a break notification on the client who has a file opened. It latter causes big latencies to other clients that are trying to open the same file. The problem reproduces when there are multiple shares from the same server mounted on the client. The processing code tries to match persistent and volatile file ids from the break notification with an open file but it skips all share besides the first one. Fix this by looking up in all shares belonging to the server that issued the oplock break.

[PATCH] blk-mq: avoid sysfs buffer overflow by too many CPU cores

by Ming Lei

It is reported that sysfs buffer overflow can be triggered in case of too many CPU cores(>841 on 4K PAGE_SIZE) when showing CPUs of hctx via /sys/block/$DEV/mq/$N/cpu_list. So use snprintf for avoiding the potential buffer overflow. This version doesn't change the attribute format, and simply stop to show CPU number if the buffer is to be overflow.

But it also isolates the unevictable pages to reclaim. Hence, we can catch the cases in shrink_page_list(). The root cause is that we scan the page tables instead of specific LRU list. and so we need to filter out the unevictable lru pages from our end.

[PATCH for-rc 1/4] IB/hfi1: Allow for all speeds higher than gen3

by Dennis Dalessandro

From: James Erwin <james.erwin(a)intel.com> The driver avoids the gen3 speed bump when the parent bus speed isn't identical to gen3, 8.0GT/s. This is not compatible with gen4 and newer speeds. Fix by relaxing the test to explicitly look for the lower capability speeds which inherently allows for all future speeds.
