Subject: [PATCH 2/2] metadump: handle multi-block directories
Date: Mon, 06 Jul 2015 13:17:20 -0500	[thread overview]
Message-ID: <559AC630.2090101@sandeen.net> (raw)
In-Reply-To: <559AC5AA.5040900@sandeen.net>

commit 6e79202b metadump: fully support discontiguous directory blocks

assembled a buffer from multiple dir blocks, and we can use that in
obfuscate_dir_data_block() to continue past the first filesystem block
and continue obfuscating the entire thing.

Without this, anything after the first block was skipped, and
remained as cleartext.
