On the old kernel:

Miao,
wrong because it is possbile that ->generation may equal to the first
variant of the next item.
When can this happen ? Can you provide a scenario to run through. ?

Hello,
I run a scrub on a 2-disc btrfs, then cancelled it, then resumed. At the end, I
expected it telling about it having finished.
But the only I get on 'btrfs scrub status /' is:

Some of the options do not IMO fit for being default, like DEGRADED,
maybe RECOVERY, maybe SKIP_BALANCE.

The current code of list_subvols() has very bad scalability, if we want to
add new filter conditions or new sort methods, we have to modify lots of code.
Beside that, the most code of list_snapshots() is similar to list_subvols(),
So I restructure list_subvols(), and split the subvolume filter fu

Hi Seto,
please could you update also the man page too ?
Why it was not provided a way to clear a *single* flag ? To me it seems a bit
too long to clear all the flag (btrfs mount-option clear) and then set the
right one.
As user interface I suggest something like chmod:
btrfs mount-option
Btrfs uses inclusive range end for lock_extent(), unlock_extent() and
related functions, so we made off-by-one errors in file clone.
This fixes it and also fixes some style problems.
