As of commit 5eb620c8 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data. Signed-off-by:

The addition of the rdma_cap_ib_mad is technically broken in ib_umad_remove_one because the loop "i" value is not a port value. This bug resulted in the ib_umad failing to properly remove its resources when the core capability functions were converted to bit fields. NOTE: e17371d73908 did not result in broken behavior on its own. It was only an issue when the implementation of rdma_cap_ib_mad was changed. Pass the port value to rdma_cap_ib_mad. Fixes: e17371d73908 ("IB/Verbs: Use management helper rdma_cap_ib_mad()") Signed-off-by: -

Previously start_port and end_port were defined in 2 places, cache.c and device.c and this prevented their use in other modules. Make these common functions, change the name to reflect the rdma name space, and update existing users. Signed-off-by:

Increase the level of documentation for the rdma_cap_* helpers introduced by Michael Wang <yun.wang@profitbricks.com>. This patch is loosely based on a patch Michael wrote to enhance the documentation of these functions, but has been significantly modified in terms of verbiage. In addition, the comments were moved from a kernel Documentation/infiniband/ file to being inline in the header file itself for the functions in question. Finally, the documentation was formated in proper kdoc format. Signed-off-by:

Two watchdog changes that came through different trees had a non conflicting conflict, that is, one changed the semantics of a variable but no actual code conflict happened. So the merge appeared fine, but the resulting code did not behave as expected. Commit 195daf66 ("watchdog: enable the new user interface of the watchdog mechanism") changes the semantics of watchdog_user_enabled, which thereafter is only used by the functions introduced by b3738d29 ("watchdog: Add watchdog enable/disable all functions"). There further appears to be a distinct lack of serialization between setting and using watchdog_enabled, so perhaps we should wrap the {en,dis}able_all() things in watchdog_proc_mutex. This patch fixes a s2r failure reported by Michal; which I cannot readily explain. But this does make the code internally consistent again. Reported-and-tested-by:
