There is a similar self-deadlock in<br /> ext4_incvert_inline_data_nolock() for data files which we&amp;#39;ll fix at<br /> the same time.<br /> <br /> A simple reproducer demonstrating the problem:<br /> <br /> mke2fs -Fq -t ext2 -O inline_data -b 4k /dev/vdc 64<br /> mount -t ext4 -o dirsync /dev/vdc /vdc<br /> cd /vdc<br /> mkdir file0<br /> cd file0<br /> touch file0<br /> touch file1<br /> attr -s BurnSpaceInEA -V abcde .<br /> touch supercalifragilisticexpialidocious
