[PATCH 1/3] xhci: Fix port resume done detection for SS ports with LPM enabled

by Mathias Nyman

A suspended SS port in U3 link state will go to U0 when resumed, but can almost immediately after that enter U1 or U2 link power save states before host controller driver reads the port status. Host controller driver only checks for U0 state, and might miss the finished resume, leaving flags unclear and skip notifying usb code of the wake. Add U1 and U2 to the possible link states when checking for finished port resume.

[PATCH v3] tpm: fix an invalid condition in tpm_common_poll

by Tadeusz Struk

The poll condition should only check response_length, because reads should only be issued if there is data to read. The response_read flag only prevents double writes. The problem was that the write set the response_read to false, enqued a tpm job, and returned. Then application called poll which checked the response_read flag and returned EPOLLIN. Then the application called read, but got nothing. After all that the async_work kicked in. Added also mutex_lock around the poll check to prevent other possible race conditions.

[PATCH] bcache: use (REQ_META|REQ_PRIO) to indicate bio for metadata

by Coly Li

In 'commit 752f66a75aba ("bcache: use REQ_PRIO to indicate bio for metadata")' REQ_META is replaced by REQ_PRIO to indicate metadata bio. This assumption is not always correct, e.g. XFS uses REQ_META to mark metadata bio other than REQ_PRIO. This is why Nix noticed that bcache does not cache metadata for XFS after the above commit. Thanks to Dave Chinner, he explains the difference between REQ_META and REQ_PRIO from view of file system developer. Here I quote part of his explanation from mailing list, REQ_META is used for metadata. REQ_PRIO is used to communicate to the lower layers that the submitter considers this IO to be more important that non REQ_PRIO IO and so dispatch should be expedited. IOWs, if the filesystem considers metadata IO to be more important that user data IO, then it will use REQ_PRIO | REQ_META rather than just REQ_META. Then it seems bios with REQ_META or REQ_PRIO should both be cached for performance optimation, because they are all probably low I/O latency demand by upper layer (e.g. file system). So in this patch, when we want to decide whether to bypass the cache, REQ_META and REQ_PRIO are both checked. Then both metadata and high priority I/O requests will be handled properly.
