In summary, the symptom is intermittent key events lost after resume on some machines with synaptics touchpad (seems this is synaptics _only_), and key events loss is due to serio port reconnect after psmouse sync lost. Removing psmouse and inserting it back during the suspend/resume process is able to work around the issue, so the difference between psmouse_connect() and psmouse_reconnect() is the key to the root cause of this problem. After comparing the two different paths, synaptics driver has its own implementation of synaptics_reconnect(), and the missing psmouse_probe() seems significant, the patch below added psmouse_probe() to the reconnect process, and has been verified many times that the issue could not be reliably reproduced. There are two PS/2 commands in psmouse_probe(): 1. PSMOUSE_CMD_GETID 2. PSMOUSE_CMD_RESET_DIS Only the PSMOUSE_CMD_GETID seems to be significant. The PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying several times. So we have only implemented this patch to issue the PSMOUSE_CMD_GETID so far. Tested-by:

This patch makes GFS2 immediately reclaim/delete all iopen glocks as soon as they're dequeued. This allows deleters to get an EXclusive lock on iopen so files are deleted properly instead of being set as unlinked. Signed-off-by:

This version has one more correction: the vmalloc calls are replaced by __vmalloc calls to preserve the GFP_NOFS flag. When GFS2's directory management code allocates buffers for a directory hash table, if it can't get the memory it needs, it currently gives a bad return code. Rather than giving an error, this patch allows it to use virtual memory rather than kernel memory for the hash table. This should make it possible for directories to function properly, even when kernel memory becomes very fragmented. Signed-off-by:

The bug was introduced with async_dio feature: trying to optimize short reads, we cut number-of-bytes-to-read to i_size boundary. Hence the following example: truncate --size=300 /mnt/file dd if=/mnt/file of=/dev/null iflag=direct led to FUSE_READ request of 300 bytes size. This turned out to be problem for userspace fuse implementations who rely on assumption that kernel fuse does not change alignment of request from client FS. The patch turns off the optimization if async_dio is disabled. And, if it's enabled, the patch fixes adjustment of number-of-bytes-to-read to preserve alignment. Note, that we cannot throw out short read optimization entirely because otherwise a direct read of a huge size issued on a tiny file would generate a huge amount of fuse requests and most of them would be ACKed by userspace with zero bytes read.

If request submission fails for an async request (i.e., get_user_pages() returns -ERESTARTSYS), we currently skip the -EIOCBQUEUED return and drop into wait_for_sync_kiocb() forever. Avoid this by always returning -EIOCBQUEUED for async requests. If an error occurs, the error is passed into fuse_aio_complete(), returned via aio_complete() and thus propagated to userspace via io_getevents(). Signed-off-by:

Fix bug introduced by commit 4582a4ab "FUSE: Adapt readdirplus to application usage patterns". We need to check for a positive dentry; negative dentries are not added by readdirplus. Secondly we need to advise the use of readdirplus on the *parent*, otherwise the whole thing is useless. Thirdly all this is only relevant if "readdirplus_auto" mode is selected by the filesystem. We advise the use of readdirplus only if the dentry was still valid. If we had to redo the lookup then there was no use in doing the -plus version. Reported-by:

Some ARM KVM VCPU ioctls require the vCPU to be properly initialized with the KVM_ARM_VCPU_INIT ioctl before being used with further requests. KVM_RUN checks whether this initialization has been done, but other ioctls do not. Namely KVM_GET_REG_LIST will dereference an array with index -1 without initialization and thus leads to a kernel oops. Fix this by adding checks before executing the ioctl handlers.

The driver's interrupt handling code is too picky in deciding whether it should handle an interrupt or not which causes completely unneeded spurious interrupts. Thus make sata_rcar_{ata|serr}_interrupt() *void*; add ATA status register read to sata_rcar_ata_interrupt() to clear an unexpected ATA interrupt -- it doesn't get cleared by writing to the SATAINTSTAT register in the interrupt mode we use. Also, in sata_rcar_ata_interrupt() we should check SATAINTSTAT register only for enabled interrupts and we should clear only those interrupts that we have read as active first time around, because else we have a race and risk clearing an interrupt that can occur between read and write of the SATAINTSTAT register and never registering it...
