| H A D | proc_sysctl.c | ef9d965b Tue Jun 09 12:08:19 CDT 2020 Christoph Hellwig <hch@lst.de> sysctl: reject gigantic reads/write to sysctl files
Instead of triggering a WARN_ON deep down in the page allocator just
give up early on allocations that are way larger than the usual sysctl
values.
Fixes: 32927393dc1c ("sysctl: pass kernel pointers to ->proc_handler")
