We need a mechanism to tell when to use the backup super_block.
To do this it needs a frame-work, and the patch #2 and #3 below
provides the same without change in the logic.
Its been found and posted to the list that check_mounted needs
access to the backup-sb. so patch #3 adds flags parameter
to the function btrfs_scan_one_device so that _only_
check_mounted can set the flag to access the backup-sb.
patch#4 below is to enable and disable acecss to backup-sb
for only certain threads
v4->v5:
Rebase with integration-20130321 and with my own changes (patch #1)
Allow check_mounted thread-path to use backup-sb
v3->v4:
Fixed some warnings introduced by patch #3 below,
sorry my mistake.
v2->v3:
Accepts David and Eric review, which would result in disabled
access to backup-superblock by default.
Dropped the patch
[PATCH 3/3] btrfs-progs: use BTRFS_SCAN_BACKUP_SB flag in btrfs_scan_one_device
Introduced a new patch
[PATCH 3/3] btrfs-progs: disable using backup superblock by default
v1->v2:
Accepts Eric and Zach review.
Separates fix into 3 patches for easy logical understanding
Anand Jain (5):
btrfs-progs: make btrfs dev scan multi path aware
btrfs-progs: Introduce flag BTRFS_SCAN_REGISTER to replace run_ioctl
btrfs-progs: Introduce flag BTRFS_SCAN_BACKUP_SB for
btrfs_read_dev_super
btrfs-progs: introduce passing flags to btrfs_scan_one_device
btrfs-progs: disable using backup superblock by default
