  "message": "kernfs: annotate different lockdep class for of-\u003emutex of writable files\n\nThe writable file /sys/power/resume may call vfs lookup helpers for\narbitrary paths and readonly files can be read by overlayfs from vfs\nhelpers when sysfs is a lower layer of overalyfs.\n\nTo avoid a lockdep warning of circular dependency between overlayfs\ninode lock and kernfs of-\u003emutex, use a different lockdep class for\nwritable and readonly kernfs files.\n\nReported-by: syzbot+9a5b0ced8b1bfb238b56@syzkaller.appspotmail.com\nFixes: 0fedefd4c4e3 (\"kernfs: sysfs: support custom llseek method for sysfs entries\")\nSuggested-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Amir Goldstein \u003camir73il@gmail.com\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n",
