CVE-2023-54311

Description
In the Linux kernel, the following vulnerability has been resolved: ext4: fix deadlock when converting an inline directory in nojournal mode In no journal mode, ext4_finish_convert_inline_dir() can self-deadlock by calling ext4_handle_dirty_dirblock() when it already has taken the directory lock. There is a similar self-deadlock in ext4_incvert_inline_data_nolock() for data files which we'll fix at the same time. A simple reproducer demonstrating the problem: mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64 mount -t ext4 -o dirsync /dev/vdc /vdc cd /vdc mkdir file0 cd file0 touch file0 touch file1 attr -s BurnSpaceInEA -V abcde . touch supercalifragilisticexpialidocious
