  "message": "ext4: fix deadlock when converting an inline directory in nojournal mode\n\nIn no journal mode, ext4_finish_convert_inline_dir() can self-deadlock\nby calling ext4_handle_dirty_dirblock() when it already has taken the\ndirectory lock.  There is a similar self-deadlock in\next4_incvert_inline_data_nolock() for data files which we\u0027ll fix at\nthe same time.\n\nA simple reproducer demonstrating the problem:\n\n    mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64\n    mount -t ext4 -o dirsync /dev/vdc /vdc\n    cd /vdc\n    mkdir file0\n    cd file0\n    touch file0\n    touch file1\n    attr -s BurnSpaceInEA -V abcde .\n    touch supercalifragilisticexpialidocious\n\nReported-by: syzbot+91dccab7c64e2850a4e5@syzkaller.appspotmail.com\nLink: https://syzkaller.appspot.com/bug?id\u003dba84cc80a9491d65416bc7877e1650c87530fe8a\nSigned-off-by: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\n",
