[ 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.
