6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Weißschuh <linux@xxxxxxxxxxxxxx>
[ Upstream commit 520713a93d550406dae14d49cdb8778d70cecdfd ]
Remove the 'table' argument from set_ownership as it is never used. This
change is a step towards putting "struct ctl_table" into .rodata and
eventually having sysctl core only use "const struct ctl_table".
The patch was created with the following coccinelle script:
@@
identifier func, head, table, uid, gid;
@@
void func(
struct ctl_table_header *head,
- struct ctl_table *table,
kuid_t *uid, kgid_t *gid)
{ ... }
No additional occurrences of 'set_ownership' were found after doing a
tree-wide search.
