Re: [dm-devel] Re: Snapshot hang problem



Hi again.

I found out another interesting thing. The stack trace attached with the
previous post was taken after a hang on a ext3 file system. Below is
another stack trace taken after a hang on a ext2 file system.
! The interesting thing is that stack traces are NOT same !
