[PATCH] cgroup: fix the retry path of cgroup_mount()

2014-04-16 Thread Li Zefan
If we hit the retry path, we'll call parse_cgroupfs_options() again, but the string we pass to it has been modified by the previous call to this function. This bug can be observed by: # mount -t cgroup -o name=foo,cpuset xxx /mnt && umount /mnt && \ mount -t cgroup -o name=foo,cpuset xxx /m

[PATCH] dmaengine: edma: No need save/restore interrupt flags during spin_lock in IRQ

2014-04-16 Thread Joel Fernandes
The vchan lock in edma_callback is acquired in hard interrupt context. As interrupts are already disabled, there's no point in save/restoring interrupt mask bit or cpsr flags. Get rid of flags local variable and use spin_lock instead of spin_lock_irqsave. Signed-off-by: Joel Fernandes --- drive

Add tunable RX interrupt trigger I/F of FIFO buffers. Serial devices are used as not only message communication devices but control or sending communication devices. For the latter uses, normally small data will be exchanged, so user applications want to receive data unit as soon as possible for re
