Subject: [PATCH v5 0/2] e2fsprogs: dump a sparse file in debugfs

Hi all,

This is the fifth try to support to dump a sparse file in debugfs.  In this
patch series the only change is to rebase the patch set against e2fsprogs
1.42.8.

v5 <- v4:
 - rebase against e2fsprogs 1.42.8

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,
						- Zheng
