      RDMA/hns: Fix sg offset non-zero issue · 60c3becf
      由 Xi Wang 提交于 
      When run perftest in many times, the system will report a BUG as follows:

   BUG: Bad rss-counter state mm:(____ptrval____) idx:0 val:-1
   BUG: Bad rss-counter state mm:(____ptrval____) idx:1 val:1

We tested with different kernel version and found it started from the the
following commit:

commit d10bcf94 ("RDMA/umem: Combine contiguous PAGE_SIZE regions in
SGEs")

In this commit, the sg->offset is always 0 when sg_set_page() is called in
ib_umem_get() and the drivers are not allowed to change the sgl, otherwise
it will get bad page descriptor when unfolding SGEs in __ib_umem_release()
as sg_page_count() will get wrong result while sgl->offset is not 0.

However, there is a weird sgl usage in the current hns driver, the driver
modified sg->offset after calling ib_umem_get(), which caused we iterate
past the wrong number of pages in for_each_sg_page iterator.

This patch fixes it by correcting the non-standard sgl usage found in the
hns_roce_db_map_user() function.

      RDMA/hns: Set reset flag when hw resetting · 726be12f
      由 Lang Cheng 提交于 
      When hw resetting, there is no response from hw when driver sending cmdq.
If driver still send cmdq to hw, the reset process may be blocked.  So
reset flag should be set to intercept the cmdq command when driver
receiving "notify down" signal.

      bus_find_device: Unify the match callback with class_find_device · 418e3ea1
      由 Suzuki K Poulose 提交于 
      There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device().  If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward.  Also with that, constify
the "data" parameter as it is passed as a const to the match function.

For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.
