This small set adds some meaningful verbosity to some
of the core/rdma_cm enumerated events. Its useful to
see the meaning of the opcodes instead of revisiting the
code for every new status/event that left our brain cache.
Changes from v3:
- Protect against "holes" in string arrays
- Restored __attribute_const__ to functions prototype
- Made string arrays rodata
Changes from v2:
- Cast to size_t instead of unsigned
- Style fix in string arrays declaration
- Removed redundant __attribute_const__
Changes from v1:
- Changed helper names ib_wc_status_msg and rdma_event_msg
- Cast input arguments to protect string buffer access
- Add svcrdma to the party
Changes from v0 (RFC):
- Moved string arrays to .c files
- Changed string helpers from macros to exported functions
- Aligned rds to generic helpers as well

It was just a little remainder for people reviewing the patches. https://xkcd.com/1172/ It's always surprising how one can use a "non-feature" and rely on it.

This small set adds some meaningful verbosity to some
of the core/rdma_cm enumerated events. Its useful to
see the meaning of the opcodes instead of revisiting the
code for every new status/event that left our brain cache.
Changes from v3:
- Protect against "holes" in string arrays
- Restored __attribute_const__ to functions prototype
- Made string arrays rodata
Changes from v2:
- Cast to size_t instead of unsigned
- Style fix in string arrays declaration
- Removed redundant __attribute_const__
Changes from v1:
- Changed helper names ib_wc_status_msg and rdma_event_msg
- Cast input arguments to protect string buffer access
- Add svcrdma to the party
Changes from v0 (RFC):
- Moved string arrays to .c files
- Changed string helpers from macros to exported functions
- Aligned rds to generic helpers as well

This small set adds some meaningful verbosity to some
of the core/rdma_cm enumerated events. Its useful to
see the meaning of the opcodes instead of revisiting the
code for every new status/event that left our brain cache.
Changes from v3:
- Protect against "holes" in string arrays
- Restored __attribute_const__ to functions prototype
- Made string arrays rodata
Changes from v2:
- Cast to size_t instead of unsigned
- Style fix in string arrays declaration
- Removed redundant __attribute_const__
Changes from v1:
- Changed helper names ib_wc_status_msg and rdma_event_msg
- Cast input arguments to protect string buffer access
- Add svcrdma to the party
Changes from v0 (RFC):
- Moved string arrays to .c files
- Changed string helpers from macros to exported functions
- Aligned rds to generic helpers as well
Sagi Grimberg (2):
IB/core, cma: Nice log-friendly string helpers
ulps: Align several ULPs to use core/rdma_cm logging helpers
