5.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Guanrui Huang <guanrui.huang@xxxxxxxxxxxxxxxxx> [ Upstream commit 382d2ffe86efb1e2fa803d2cf17e5bfc34e574f3 ] This BUG_ON() is useless, because the same effect will be obtained by letting the code run its course and vm being dereferenced, triggering an exception. So just remove this check.
