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( ... ) Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler") Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Cc: Christoph Hellwig <hch@lst.de> Cc: Al Viro <viro@zeniv.linux.org.uk> Link: https://lkml.kernel.org/r/20200825093647.24263-1-tklauser@distanz.ch Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
