Subject: linux-next: manual merge of the akpm tree with Linus' tree
Date: Tue, 1 Nov 2011 19:16:02 +1100
Message-ID: <20111101191602.bb64237e8ab87671d3964ca9@canb.auug.org.au> (raw)

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
fs/direct-io.c between commit eb28be2b4c0a ("direct-io: separate fields
only used in the submission path from struct dio") from Linus' tree and
commit "fs/direct-io.c: salcuate fs_count correctly in get_more_blocks()"
from the akpm tree.

I fixed it up (see below) and can carry the fix as necessary.

Cheers,
Stephen Rothwell                    sfr@canb.auug.org.au
