Some programs like btrfsck should not be run on a mounted filesystem. This patch adds a check in btrfs_open_devices() for the mount status of every device belonging to the filesystem. The function check_mount() gets improved support for loopback devices. It now detects if the program is run on the file that is being used by the loopback device.

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing

NOTE: in order to apply this patch you should: git mv btrfsck.c cmd-fsck.c This patch moves btrfsck in to "btrfs fsck". It also adds support for symlinks to the btrfs binary to retain compablity, =) I think something should be done to the help description but i''m not sure what...
