Subject: [PATCH 01/22] xfs: consider minlen sized extents in xfs_rtallocate_extent_block
Date: Mon, 18 Dec 2023 05:57:17 +0100	[thread overview]
Message-ID: <20231218045738.711465-2-hch@lst.de> (raw)
In-Reply-To: <20231218045738.711465-1-hch@lst.de>

minlen is the lower bound on the extent length that the caller can
accept, and maxlen is at this point the maximal available length.
This means a minlen extent is perfectly fine to use, so do it.  This
matches the equivalent logic in xfs_rtallocate_extent_exact that also
accepts a minlen sized extent.
