[PATCH v2 11/18] sysctl: treewide: constify ctl_table_header::ctl_table_arg

From: Thomas Weißschuh

Next message: Thomas Weißschuh: "[PATCH v2 13/18] sysctl: move sysctl type to ctl_table_header"
Previous message: Thomas Weißschuh: "[PATCH v2 18/18] sysctl: constify standard sysctl tables"
In reply to: Thomas Weißschuh: "[PATCH v2 18/18] sysctl: constify standard sysctl tables"
Next in thread: Thomas Weißschuh: "[PATCH v2 13/18] sysctl: move sysctl type to ctl_table_header"
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

In a future commit the sysctl core will only use
"const struct ctl_table". As a preparation for that adapt the
ctl_table_arg member.
