[PATCH 00/18] virtiofs: Fix various races and cleanups round 1
Hi,
Michael Tsirkin pointed out issues w.r.t various locking related TODO
items and races w.r.t device removal.
In this first round of cleanups, I have taken care of most pressing
issues.
These patches apply on top of following.
git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git#virtiofs-v4
I have tested these patches with mount/umount and device removal using
qemu monitor. For

[PATCH v8 00/18] Add support for FDMA DMA controller and slim core rproc found on STi chipsets
Hi Vinod, Bjorn, Patrice,
This patchset adds support for the Flexible Direct Memory Access (FDMA) core
found on STi chipsets from STMicroelectronics. The FDMA is a slim core CPU
with a dedicated firmware. It is a general purpose DMA controller supporting
16 independent channels and data can be moved from memory to memory or between
memory and paced latency critical real time targets.
