[PATCH v3 0/2] sysctl: treewide: prepare ctl_table_root for ctl_table constification

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


The two patches were previously submitted on their own.
In commit f9436a5d0497
("sysctl: allow to change limits for posix messages queues")
a code dependency was introduced between the two callbacks.
This code dependency results in a dependency between the two patches, so
now they are submitted as a series.

The series is meant to be merged via the sysctl tree.

There is an upcoming series that will introduce a new implementation of
.set_ownership and .permissions which would need to be adapted [0].

These changes ere originally part of the sysctl-const series [1].
To slim down that series and reduce the message load on other
maintainers to a minimum, the patches are split out.
