Re: mprotect_reduce_protid_on kernel parameter not shown
PHKL_41507:
This patch is a member of a set of two patches, needed to disable the performance improvements provided by PHKL_39901 and PHKL_39902 by default.
They also provide a new kernel dynamic tunable, mprotect_reduce_protid_on, to enable or disable them, as required. The patch, PHKL_41231, contains the core functionality and this patch, PHKL_41507, contains the man page for the dynamic tunable.
thanks

Re: mprotect_reduce_protid_on kernel parameter not shown
or >=PHKL_39901 and PHKL_39902 on 11iv2 (11.23)
But it is advised to get the last replacements for those patches. 11.31 PHKL_41972
11.23 PHKL_41807 and PHKL_41231
