There is a similar self-deadlock in\next4_incvert_inline_data_nolock() for data files which we'll 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",
