commit 1a37079c236d55fb31ebbf4b59945dab8ec8764c upstream.
This reverts commit e46e01eebbbc ("selinux: stop passing MAY_NOT_BLOCK to the AVC upon follow_link"). The correct fix is to instead fall back to ref-walk if audit is required irrespective of the specific audit data type. This is done in the next commit.

This patch should be accompanied by commit 0188d5c025ca8fe756ba3193bd7d150139af5a88 ("selinux: fall back to ref-walk if audit is required"). The former is reverting an incorrect fix for bda0be7ad994 ("security: make inode_follow_link RCU-walk aware"), the latter is providing the correct fix for it.
Thanks for letting me know, now queued up for both trees.
