2017-03-02block: Initialize bd_bdi on inode initializationJan Kara1-2/+4
So far we initialized bd_bdi only in bdget(). That is fine for normal bdev inodes however for the special case of the root inode of blockdev_superblock that function is never called and thus bd_bdi is left uninitialized. As a result bdev_evict_inode() may oops doing bdi_put(root->bd_bdi) on that inode as can be seen when doing: mount -t bdev none /mnt Fix the problem by initializing bd_bdi when first allocating the inode and then reinitializing bd_bdi in bdev_evict_inode(). Thanks to syzkaller team for finding the problem.

2017-03-02loop: fix LO_FLAGS_PARTSCAN hangOmar Sandoval1-7/+8
loop_reread_partitions() needs to do I/O, but we just froze the queue, so we end up waiting forever. This can easily be reproduced with losetup -P. Fix it by moving the reread to after we unfreeze the queue.

2017-03-02nvme: Complete all stuck requestsKeith Busch3-5/+79
If the nvme driver is shutting down its controller, the drievr will not start the queues up again, preventing blk-mq's hot CPU notifier from making forward progress. To fix that, this patch starts a request_queue freeze when the driver resets a controller so no new requests may enter. The driver will wait for frozen after IO queues are restarted to ensure the queue reference can be reinitialized when nvme requests to unfreeze the queues. If the driver is doing a safe shutdown, the driver will wait for the controller to successfully complete all inflight requests so that we don't unnecessarily fail them. Once the controller has been disabled, the queues will be restarted to force remaining entered requests to end in failure so that blk-mq's hot cpu notifier may progress.

2017-03-02ath10k: search SMBIOS for OEM board file extensionWaldemar Rymarkiewicz2-3/+117
Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified, among others, by device and sybsystem ids. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name Extension to specify the extension/variant name. The driver will take the extension suffix into consideration and will load the right (non-default) board data file if necessary. If it is unnecessary to use extension board data file, please leave the SMBIOS field blank and default configuration will be used. Example: If a default board data file for a specific board is identified by a string "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310" then the OEM specific data file, if used, could be identified by variant suffix: "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310,variant=DE_1AB" If board data file name extension is set but board-2.bin does not contain board data file for the variant, the driver will fallback to the default board data file not to break backward compatibility. This was first applied in commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension") but later reverted in commit 005c3490e9db ("Revert "ath10k: Search SMBIOS for OEM board file extension"". This patch is now otherwise the same as commit f2593cb1b291 except the regression fixed. Signed-off-by: Waldemar Rymarkiewicz <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
