David,
Thanks for the comments
As of now with out this patch the sysfs interface under dir
/sys/fs/btrfs/<fsid>/devices is just link to the block devs.
At this point it's part of the sysfs ABI and should not be changed.
can't we lean on the experimental clause to change it either ?
practically is there anything thats already depending on this
dev link ?
Example:
/sys/fs/btrfs/devmap/by-id/
contains directories with integer numbers that represent devices
This won't work.
devid isn't unique at the btrfs-module level. its under fsid.
[IMO. its ok if the ideas doesn't match ;-) as in any case I
will be doing it in the way the most want]
When user come to sys/fs/btrfs their "main" reference of identifying
a "volume" is the FSID/label. not individual disks.
Of course disks are the sub-references of a volume.
I suggest - first do the way btrfs-kernel does (which is - group disks
under fsid) And later create abstraction links as needed which we don't
have to worry about as of now.
Thanks, Anand
