Hi all,

This is the fourth try to support to dump a sparse file in debugfs.  In this
patch series the only change is using ext2fs_llseek() in dump_file to get a
better portability.

Hi Ted,

Could please take a look at this patch series?  It has been sent out
for a long time.  I have forgotten it completely until I clean up my
e2fsprogs tree.  I try to rebase this patch series against the latest
master branch of e2fsprogs tree, and it can be applied without any
changes.

Thanks,

v4 <- v3:
 - call ext2fs_llseek() in dump_file to seek to the next data because of better
   portability

v3 <- v2:
 - use extent interfaces to handle extent-based file in seek_data/hole function
 - call ext2fs_file_llseek() to retrieve current offset in dump_file()

v2 <- v1:
 - split original patch into two parts.
 - make code clearly according to Ted's suggestions

Regards,
