Subject: [PATCH v1 00/37] e2fsprogs: Add metadata checksumming
Date: Wed, 31 Aug 2011 17:35:09 -0700 [thread overview]
Message-ID: <20110901003509.1176.51159.stgit@elm3c44.beaverton.ibm.com> (raw)
Hi all,
This patchset adds support in e2fsprogs for attaching crc32c checksums to most
of the ext4 metadata objects. A full design document is on the ext4 wiki[1].
Please see the cover letter for the kernel patches for a more thorough summary
of this work.
Please have a look at the design document and patches, and please feel free to
suggest any changes. I will be at LPC next week if anyone wishes to discuss,
debate, or protest.
