2010-03-21 18:25:34 Kees Cook description I'm seeing huge latency sometimes when unmounting ext4 partitions. Steps that triggered this most recently: sudo -s cd /tmp dd if=/dev/zero of=test.ext4 bs=1 count=1 seek=1G mkfs.ext4 test.ext4 mkdir /mnt/test mount -o loop text.ext4 /mnt/test echo $(seq 65536) | (cd /mnt/test; xargs touch) time umount /mnt/test I'm seeing upwards of 5 minutes for the umount to finish. I'm seeing huge latency sometimes when unmounting ext4 partitions.
