Another attempt to rationalize description of MPOL_DEFAULT.
|
||||
|
||||
Since ~2.6.25, the system default memory policy is "local allocation".
|
||||
MPOL_DEFAULT itself is a request to remove any non-default policy and
|
||||
"fall back" to the surrounding context. Try to say that without delving
|
||||
into implementation details.

Add discussion of mempolicy mode flags to set_mempolicy(2).

This adds another reason for EINVAL.

Changes to individual pages (math functions)

Various changes here following on from the big update to the

math pages in the previous release. Test results going back

glibc 2.3.2 (so far) allowed updates to various pages to note
|
||||
changes in historical behavior for error reporting by math
|

functions. Thanks to the following people for providing me
