The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will also be merged in the next major kernel release during the merge window. If you have any questions about this process, please let me know. >From 05c8f1b67e67dcd786ae3fe44492bbc617b4bd12 Mon Sep 17 00:00:00 2001 From: James Buren Date: Wed, 13 Oct 2021 20:55:04 -0500 Subject: usb-storage: Add compatibility quirk flags for iODD 2531/2541 These drive enclosures have firmware bugs that make it impossible to mount a new virtual ISO image after Linux ejects the old one if the device is locked by Linux. Windows bypasses this problem by the fact that they do not lock the device. Add a quirk to disable device locking for these drive enclosures.
