Package: fuseext2
Version: 0.4-1.1
Severity: normal

Dear Maintainer,


   * What led up to the situation?

When using fuseext2 for mounting filesystem with block size > 4K, 1 CPU core is
at 100% and directory with mount point is busy (when file image is mounted,
then directory with this file is busy too).

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

i.e.:

$ dd if=/dev/zero of=ext4-bs64k.img bs=1M seek=1M count=0

$ sudo /sbin/mkfs.ext4 -L TestExtFS -b 65536 ext4-bs64k.img

$ fuseext2 ext4-bs64k.img /mount/somewhere/you/want

   * What was the outcome of this action?

Filesystem is mounted without errors, but when any operation (i.e. ls -l) on
mount point cause 100% of 1 CPU core and there is no expected output from
operation.

   * What outcome did you expect instead?

Working with mounted filesystem as usually (ls, cp, mv, mkdir, rm, rmdir, etc.)


Sincerely

Jarda
