  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\next4: 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'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",
