xfs: Add inode pin counts to traces
We don't record pin counts in inode events right now, and this makes it difficult to track down problems related to pinning inodes. Add the pin count to the inode trace class and add trace events for pinning and unpinning inodes. Signed-off-by: Dave Chinner <dchinner@redhat.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
