Subject: CVE request: kernel: splice: fix bad unlock_page() in error case

Hi Steve,

This bug requires a CVE name. Please allocate one.

This upstream commit addressed a user triggerable DoS:

[PATCH] splice: fix bad unlock_page() in error case

If add_to_page_cache_lru() fails, the page will not be locked. But
splice jumps to an error path that does a page release and unlock,
causing a BUG() in unlock_page().

(different issue, but same reproducer)


Thanks, Eugene
