Cover letter [PATCH v2 0/7] IB/srp: Second series of patches for kernel v4.7

Hello Doug,

Since the first eight patches of the patch series "[PATCH 0/11] More SRP patches for kernel v4.7" have already been applied I'm reposting version two of the reworked remaining patches. These patches are:

0001-IB-srp-Print-ib_srp-prefix-once.patch 0002-IB-srp-Fix-a-memory-descriptor-leak-in-an-error-path.patch 0003-IB-srp-Fix-srp_create_target-error-handling.patch 0004-IB-core-Enhance-ib_map_mr_sg.patch 0005-IB-srp-Swap-two-code-blocks-in-srp_add_one.patch 0006-IB-srp-Prevent-mapping-failures.patch 0007-IB-srp-Do-not-register-memory-if-never_register-has-.patch

The changes compared to v1 of this patch series are:
* Fixed a bug in patch 4/7, the patch that modifies ib_map_mr_sg().
* Added code that checks how many data has been mapped in patch 6/7. This code can be enabled and disabled dynamically via the dynamic debug mechanism.
* Added a seventh patch that introduces the never_register parameter.

This patch series is based on Christoph's RDMA read/write API rework patch series.

A git tree with these patches is available at https://github.com/bvanassche/linux/commits/srp-initiator-for-next.

Thanks,

Bart.
