Alex Elder 8a262e573d xfs: use scalable vmap API ... Re-apply a commit that had been reverted due to regressions that have since been fixed. From 95f8e302c0 Mon Sep 17 00:00:00 2001 From: Nick Piggin <npiggin@suse.de> Date: Tue, 6 Jan 2009 14:43:09 +1100 Implement XFS's large buffer support with the new vmap APIs. See the vmap rewrite (db64fe02) for some numbers. The biggest improvement that comes from using the new APIs is avoiding the global KVA allocation lock on every call. Signed-off-by: Nick Piggin <npiggin@suse.de> Reviewed-by: Christoph Hellwig <hch@infradead.org> Signed-off-by: Lachlan McIlroy <lachlan@sgi.com> Only modifications here were a minor reformat, plus making the patch apply given the new use of xfs_buf_is_vmapped().
