Subject: [PATCH 0/2 v3] dump a sparse file in debugfs

Hi folks,

This is the third try to support to dump a sparse file in debugfs.  In this
patch series ext2fs_file_llseek_data/hole() functions are defined to let the
caller seek to the next data/hole directly.  Meanwhile in dump_file() it is
changed to handle sparse file.

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
