linux-next: manual merge of the ext3 tree with Linus' tree

[Stephen Rothwell <sfr@canb.auug.org.au>]

Hi Jan,

Today's linux-next merge of the ext3 tree got a conflict in fs/super.c
between commits b20bd1a5e78af267dc4b6e1ffed48d5d776302c5 ("get rid of
S_BIAS"), 1712ac8fda7d8bc4dc921f5777b7423aacad7263 ("Saner locking around
deactivate_super()") and e1e46bf1866317d4f86f66bf18d3f07317d9f9ee ("Trim
includes in fs/super.c") from Linus' tree and commits
c3134141c78d5ea233a08b703b553e70cfb5c585 ("quota: move unmount handling
into the filesystem") and cdb89ca659f5a39edf88f3c55e545ea3347533d1
("quota: explicitly set ->dq_op and ->s_qcop") from the ext3 tree.

I fixed it all up (see below) and can carry the fix for a while.
