File 0104-Ignore-the-error-ENXIO-and-ENOMEDIUM-during-a-devs-s.patch of Package btrfsprogs
From da911929cf232b81a4e2dcffbb26dc3cc6f222af Mon Sep 17 00:00:00 2001 From: Goffredo Baroncelli <kreijack@inwind.it> Date: Fri, 21 Oct 2011 19:00:28 +0200 Subject: [PATCH 05/35] Ignore the error ENXIO and ENOMEDIUM during a devs scan Ignore the error ENXIO (device don't exists) and ENOMEDIUM ( No medium found -> like a cd tray empty) in the function btrfs_scan_one_dir. This avoids spurios errors due to an empty CD or a block device node without a device (which is frequent in a static /dev).
