Subject: [PATCH 0/2] Deduplicate bin_attribute simple read() callbacks
Date: Sat, 6 Apr 2024 15:52:00 +0200 [thread overview]
Message-ID: <cover.1712410202.git.lukas@wunner.de> (raw)
For my upcoming PCI device authentication v2 patches, I have the need
to expose a simple buffer in virtual memory as a bin_attribute.
It turns out we've duplicated the ->read() callback for such simple
buffers a fair number of times across the tree.
So instead of reinventing the wheel, I decided to introduce a common
helper and eliminate all duplications I could find.
I'm open to a bikeshedding discussion on the sysfs_bin_attr_simple_read()
name. ;)

sysfs: Add sysfs_bin_attr_simple_read() helper
treewide: Use sysfs_bin_attr_simple_read() helper
