Subject: [PATCH v2 0/4] ext4: Add XIP functionality
Date: Thu, 5 Dec 2013 13:02:44 -0700 [thread overview]
Message-ID: <1386273769-12828-1-git-send-email-ross.zwisler@linux.intel.com> (raw)
This patch series addresses the comments received from the first revision.
We didn't change our use of ext4_get_block() to ext4_map_blocks() because it
seems like we would need to add code to deal with journal entries, similar to
what is done in _ext4_get_block(). This seemed more complicated than using a
temporary struct buffer_head on the stack - please let us know if you
disagree.

xip: Add xip_zero_page_range
