Subject: xfs: reduce the size of nr_ops for refcount btree cursors
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=efb79ea31067ae3dd0f348eb06e6b9a5e9907078;p=linux.git

xfs: reduce the size of nr_ops for refcount btree cursors

We're never going to run more than 4 billion btree operations on a
refcount cursor, so shrink the field to an unsigned int to reduce the
structure size.  Fix whitespace alignment too.
