Merge branch 'raw_dumps' into rdma.git for-next

Maor Gottlieb says:

====================
The following series adds support to get the RDMA resource data in RAW
format. The main motivation for doing this is to enable vendors to return
the entire QP/CQ/MR data without a need from the vendor to set each
field separately.
====================

Based on the mlx5-next branch at
git://git.kernel.org/pub/scm/linux/kernel/git/mellanox/linux
due to dependencies

RDMA/mlx5: Add support to get MR resource in RAW format
RDMA/mlx5: Add support to get CQ resource in RAW format
RDMA/mlx5: Add support to get QP resource in RAW format
RDMA: Add support to dump resource tracker in RAW format
RDMA: Add dedicated CM_ID resource tracker function
RDMA: Add dedicated QP resource tracker function
RDMA: Add a dedicated CQ resource tracker function
RDMA: Add dedicated MR resource tracker function
RDMA/core: Don't call fill_res_entry for PD

"This is the second round of ext4 commits for 5.8 merge window [1].

It includes the per-inode DAX support, which was dependant on the DAX
infrastructure which came in via the XFS tree, and a number of
regression and bug fixes; most notably the "BUG: using
smp_processor_id() in preemptible code in ext4_mb_new_blocks" reported
by syzkaller"

ext4: support xattr gnu.* namespace for the Hurd

The Hurd gained[0] support for moving the translator and author
fields out of the inode and into the "gnu.*" xattr namespace.

In anticipation of that, an xattr INDEX was reserved[1]. The Hurd has
now been brought into compliance[2] with that.

This patch adds support for reading and writing such attributes from
Linux; you can now do something like

mkdir -p hurd-root/servers/socket
touch hurd-root/servers/socket/1
setfattr --name=gnu.translator --value='"/hurd/pflocal\0"' \
hurd-root/servers/socket/1
getfattr --name=gnu.translator hurd-root/servers/socket/1
# file: 1
gnu.translator="/hurd/pflocal"

to setup a pipe translator, which is being used to create[3] a
vm-image for the Hurd from GNU Guix.
