For review and feedback.
- Provides interface to read struct btrfs_fs_devices and btrfs_device
members.
- This applies on top of Dave integration branch plus the sysfs
framework patch set
[PATCH 00/26 v4] provide framework so that sysfs attributs from the fs_devices can be added
(find it in the ML)
- here the introduced sysfs path:
/sys/fs/btrfs/<fsid>/device/<uuid>/<attr>
seems to be too long, having fsid is fine but uuid isn't user
friendly, I am open to suggestion for anything better. But kindly
think about the following before suggesting
there is already the path /sys/fs/btrfs/<fsid>/device/sd<x>
which points to the sysfs sd<x>, thats useless, but got in first,
it can't be replaced. So sd<x> dir can't be used.
- Known intermittent bugs (to be fixed before intergation)
. kmem leak after running the device-test-suite.
. null deref, on rcu string during show of uuid/name
