From 8ded348cf85fd8572d4ee7fc9d0cad150f4fc2be Mon Sep 17 00:00:00 2001 From: Chris Mason <chris.mason@oracle.com> Date: Tue, 21 Feb 2012 15:33:20 -0500 Subject: [PATCH 16/18] Btrfs: use /proc/partitions scanning for btrfs_scan_for_fsid btrfs_scan_for_fsid is used by open_ctree and by mkfs when it is checking for mounted devices. It currently scans all of /dev, which is rarely the right answer.
