Subject: Re: [PATCH 00/10] btrfs: make lseek and fiemap much more efficient
Date: Wed, 7 Sep 2022 02:12:55 -0700 [thread overview]
Message-ID: <Yxhgl/p7xF1UfqHO@infradead.org> (raw)
In-Reply-To: <cover.1662022922.git.fdmanana@suse.com>
On a related question: have you looked into using iomap for fiemap
seek in btrfs? This won't remove the need for fixing some of the
underlying algorithmic complexity, but it should allow to shed some
boilerplate code and reuse bits used by other disk based file systems.
