nvme: allow 64-bit results in passthru commands2019-10-29T08:21:31+00:00Marta Rybczynskamrybczyn@kalray.eu2019-09-24T13:14:52+00:00urn:sha1:76d609da9ed1cc0dc780e2b539d7b827ce28f182
[ Upstream commit 65e68edce0db433aa0c2b26d7dc14fbbbeb89fbb ]
It is not possible to get 64-bit results from the passthru commands,
what prevents from getting for the Capabilities (CAP) property value.
As a result, it is not possible to implement IOL's NVMe Conformance
test 4.3 Case 1 for Fabrics targets [1] (page 123).
This issue has been already discussed [2], but without a solution.
This patch solves the problem by adding new ioctls with a new
passthru structure, including 64-bit results. The older ioctls stay
unchanged.

sched: Add __ASSEMBLY__ guards around struct clone_args2019-10-11T16:36:20+00:00Seth Forsheeseth.forshee@canonical.com2019-09-17T07:18:53+00:00urn:sha1:17c952422eca1b43ab10353fc70c9eb5dfc2233c
commit 61129dd29f7962f278b618a2a3e8fdb986a66dc8 upstream.
The addition of struct clone_args to uapi/linux/sched.h is not protected
by __ASSEMBLY__ guards, causing a failure to build from source for glibc
on RISC-V. Add the guards to fix this.

The commit fe3475af3bdf ("net: rds: add per rds connection cache
statistics") adds cache_allocs in struct rds_info_rdma_connection
as below:
struct rds_info_rdma_connection {
...
__u32 rdma_mr_max;
__u32 rdma_mr_size;
__u8 tos;
__u32 cache_allocs;
};
The peer struct in rds-tools of struct rds_info_rdma_connection is as
below:
struct rds_info_rdma_connection {
...
uint32_t rdma_mr_max;
uint32_t rdma_mr_size;
uint8_t tos;
uint8_t sl;
uint32_t cache_allocs;
};
The difference between userspace and kernel is the member variable sl.
In the kernel struct, the member variable sl is missing. This will
introduce risks. So it is necessary to use this commit to avoid this risk.

jffs2: Remove C++ style comments from uapi header2019-08-22T15:24:51+00:00Masahiro Yamadayamada.masahiro@socionext.com2019-06-18T03:09:26+00:00urn:sha1:7542c6dedbc1caa284ca4cbd6b64f99023ff1b97
Linux kernel tolerates C++ style comments these days. Actually, the
SPDX License tags for .c files start with //.
On the other hand, uapi headers are written in more strict C, where
the C++ comment style is forbidden.
I simply dropped these lines instead of fixing the comment style.
This code has been always commented out since it was added around
Linux 2.4.9 (i.e. commented out for more than 17 years).
'Maybe later...' will never happen.
