Subject: [PATCH v3 0/3] Add XIP support to ext4
Date: Tue, 17 Dec 2013 14:18:25 -0500 [thread overview]
Message-ID: <cover.1387307259.git.matthew.r.wilcox@intel.com> (raw)
For v3, we've addressed the problem with unwritten extents that Dave
Chinner pointed out. Rather than testing bh_unwritten() as he suggested,
I opted for checking !buffer_mapped() as block_read_full_page() in
fs/buffer.c does. While I'm in that function I renamed the buffer_head
from 'tmp' to 'bh' to follow normal usage.
I also folded the "ext4: Add xip hole punching" patch into the main
"Add XIP functionality" patch since otherwise we're introducing broken
functionality in the middle of the series.

Fix XIP fault vs truncate race
