From 11941610b06820c4af7f1ff12071f159b3bf771d Mon Sep 17 00:00:00 2001 From: Al Viro Date: Fri, 22 Aug 2025 13:07:43 -0400 Subject: [PATCH] finish_automount(): simplify the ELOOP check It's enough to check that dentries match; if path->dentry is equal to m->mnt_root, superblocks will match as well.
