The variable 'is_btrfs' is declared as an integer but could be a boolean
instead.

The struct open_ctree_flags currently holds arguments for
open_ctree_fs_info(), it can be confusing when mixed with a local variable
named open_ctree_flags as below in the function cmd_inspect_dump_tree().
cmd_inspect_dump_tree()
::
struct open_ctree_flags ocf = { 0 };
::
unsigned open_ctree_flags;
So rename struct open_ctree_flags to struct open_ctree_args.

v3: Also rename struct open_ctree_args' variable to oca.

Drop the devid argument; instead, it can be fetched from the disk_super
argument.

Is there something wrong with the thread?
This patch is showing 5/7 but the next is only 6/6.
The same problem happens to your tune patchset too, which seems worse,
as what I got is 1/5, 1/1, 3/5, 3/5 and 5/5.
Thanks,

Sorry for the confusion. Please read the patch number as 5/6.

I noticed it a little late, but 1/1 should be updated to 2/5.

The function check_where_mounted() scans the system for all other btrfs
devices, which is necessary for its operation.
However, in certain cases, devices remained in the scanned state is
undesirable.
So introduces the 'noscan' argument to make devices unscanned before
return.
