The is only ever set to non-zero if the MR is from the cache, and if it is cached then the order is in cached_ent->order. Make it clearer that use_umr_mtt_update() only returns true for cached MRs and remove the redundant data. Link: https://lore.kernel.org/r/20201026131936.1335664-2-leon@kernel.orgSigned-off-by:

Make changes to use sysfs_emit in the RDMA code as cocci scripts can not be written to handle _all_ the possible variants of various sprintf family uses in sysfs show functions. While there, make the code more legible and update its style to be more like the typical kernel styles. Miscellanea: o Use intermediate pointers for dereferences o Add and use string lookup functions o return early when any intermediate call fails so normal return is at the bottom of the function o mlx4/mcg.c:sysfs_show_group: use scnprintf to format intermediate strings Link: https://lore.kernel.org/r/f5c9e4c9d8dafca1b7b70bd597ee7f8f219c31c8.1602122880.git.joe@perches.comSigned-off-by:

The doorbell needs to store PI information into QPC, so the RoCEE should wait for the results of storing, that is, it needs two bus operations to complete a doorbell. When ROCEE is in SDI mode, multiple doorbells may be interlocked because the RoCEE can only handle bus operations serially. So a flag to mark if HIP09 is working in SDI mode is added. When the SDI flag is set, the ROCEE will ignore the PI information of the doorbell, continue to fetch wqe and verify its validity by it's owner_bit.

Currently, iser target support max IO size of 16MiB by default. For some adapters, allocating this amount of resources might reduce the total number of possible connections that can be created. For those adapters, it's preferred to reduce the max IO size to be able to create more connections. Since there is no handshake procedure for max IO size in iser protocol, set the default max IO size to 1MiB and add a module parameter for enabling the option to control it for suitable adapters.

The code which limited the number of unacknowledged PSNs was incorrect. The PSNs are limited to 24 bits and wrap back to zero from 0x00ffffff. The test was computing a 32 bit value which wraps at 32 bits so that qp->req.psn can appear smaller than the limit when it is actually larger. Replace '>' test with psn_compare which is used for other PSN comparisons and correctly handles the 24 bit size.

Since a while now the uverbs layer checks if the driver implements a function before allowing the ucmd to proceed. This largely obsoletes the cmd_mask stuff, but there is some tricky bits in drivers preventing it from being removed. Remove the easy elements of uverbs_ex_cmd_mask by pre-setting them in the core code. These are triggered soley based on the related ops function pointer. query_device_ex is not triggered based on an op, but all drivers already implement something compatible with the extension, so enable it globally too.

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms. Conversion done using the script at: https://lore.kernel.org/lkml/75393e5ddc272dc7403de74d645e6c6e0f4e70eb.camel@perches.com/2-convert_section.plSigned-off-by:Nick Desaulniers <ndesaulniers@gooogle.com> Reviewed-by:
