6.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christoph Hellwig hch@lst.de
[ Upstream commit 8442d94b8ac8d5d8300725a9ffa9def526b71170 ]
allocate_segment_by_default has just two callers, which use very different code pathes inside it based on the force paramter. Just open code the logic in the two callers using a new helper to decided if a new segment should be allocated.
