The patch titled Subject: fork: adjust sysctl_max_threads definition to match prototype has been removed from the -mm tree. Its filename was fork-adjust-sysctl_max_threads-definition-to-match-prototype.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Tobias Klauser <tklauser@xxxxxxxxxx> Subject: fork: adjust sysctl_max_threads definition to match prototype Commit 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") changed ctl_table.proc_handler to take a kernel pointer. Adjust the definition of sysctl_max_threads to match its prototype in linux/sysctl.h which fixes the following sparse error/warning: kernel/fork.c:3050:47: warning: incorrect type in argument 3 (different address spaces) kernel/fork.c:3050:47: expected void * kernel/fork.c:3050:47: got void [noderef] __user *buffer kernel/fork.c:3036:5: error: symbol 'sysctl_max_threads' redeclared with different type (incompatible argument 3 (different address spaces)): kernel/fork.c:3036:5: int extern [addressable] [signed] [toplevel] sysctl_max_threads( ... ) kernel/fork.c: note: in included file (through include/linux/key.h, include/linux/cred.h, include/linux/sched/signal.h, include/linux/sched/cputime.h): ./include/linux/sysctl.h:242:5: note: previously declared as: ./include/linux/sysctl.h:242:5: int extern [addressable] [signed] [toplevel] sysctl_max_threads( ... ) Link: https://lkml.kernel.org/r/20200825093647.24263-1-tklauser@xxxxxxxxxx Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") Signed-off-by: Tobias Klauser <tklauser@xxxxxxxxxx> Cc: Christoph Hellwig <hch@xxxxxx> Cc: Al Viro <viro@xxxxxxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- kernel/fork.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/kernel/fork.c~fork-adjust-sysctl_max_threads-definition-to-match-prototype +++ a/kernel/fork.c @@ -3014,7 +3014,7 @@ int unshare_files(struct files_struct ** } int sysctl_max_threads(struct ctl_table *table, int write, - void __user *buffer, size_t *lenp, loff_t *ppos) + void *buffer, size_t *lenp, loff_t *ppos) { struct ctl_table t; int ret; _ Patches currently in -mm which might be from tklauser@xxxxxxxxxx are
