Subject: "block_dump, bd" in debugfs
Date: Wed, 26 Jun 2013 23:05:13 -0400 [thread overview]
Message-ID: <20130627030513.217820@gmx.com> (raw)
Hi,
When I use "block_dump" to dump certain block. I got 12288 bytes dumped.
But I checked my block_size, it is 4k.
At debugfs interactive prompt, it says "Dump contents of a block". So I am confused here.
I read the code, it has for (i=0; i<current_fs->blocksize; i+=16) ,I don't understand why I can get 12k output.
Also at the beginning of each line. The output pattern is "0000, 0020, 0040, 0060, 0100, 0120", where are numbers such as"0080,"?
Thanks in advance for any explanation.
