  "message": "ext4: add more paranoia checking in ext4_expand_extra_isize handling\n\ncommit 4ea99936a1630f51fc3a2d61a58ec4a1c4b7d55a upstream.\n\nIt\u0027s possible to specify a non-zero s_want_extra_isize via debugging\noption, and this can cause bad things(tm) to happen when using a file\nsystem with an inode size of 128 bytes.\n\nAdd better checking when the file system is mounted, as well as when\nwe are actually doing the trying to do the inode expansion.\n\nLink: https://lore.kernel.org/r/20191110121510.GH23325@mit.edu\nReported-by: syzbot+f8d6f8386ceacdbfff57@syzkaller.appspotmail.com\nReported-by: syzbot+33d7ea72e47de3bdf4e1@syzkaller.appspotmail.com\nReported-by: syzbot+44b6763edfc17144296f@syzkaller.appspotmail.com\nSigned-off-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nCc: stable@kernel.org\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n",
