assert "timo || _kernel_lock_held()" failed in kern_synch.c
Status: fixed on 2019/08/13 12:07
Reported-by: syzbot+57588681ca9e3e9ba926@syzkaller.appspotmail.com
Fix commit: 93e05fce3bab Revert unlock of lseek(2) since vn_lock() could end up calling tsleep() which is not allowed without holding the kernel lock. Otherwise, wakeups could be lost.
First crash: 712d, last: 712d
