Revision 63ce5f552beb9bdb41546b3a26c4374758b21815 authored by Pan Bian on 01 February 2019, 22:21:26 UTC, committed by Linus Torvalds on 01 February 2019, 23:46:24 UTC
autofs_expire_run() calls dput(dentry) to drop the reference count of dentry. However, dentry is read via autofs_dentry_ino(dentry) after that. This may result in a use-free-bug. The patch drops the reference count of dentry only when it is never used.
