Re: btrfs: block rsv returned -28

wrong, I tryed to wait until "Load average" got near to zero (couple of minutes)
before unmounting and it changed nothing. None of thoses subvolumes have any data inside
so deleting should be trivial and quick.

Got the kernel backtrace "while" doing the deletes. Not after.

Hi,

I ran a quite heavy script who create 10,000 subvolumes and then delete
thoses 10,000 subvolumes.

No problems in the "create" part, but at the "delete" part
I got several traceback from the kernel:

and finally the partition cannot be unmounted and I had to reboot.

well, it's probably not that important, who the hell will be deleting 10,000
subvolumes
in a 2 minutes timeframe ?

Deletion works in the background, and involves a walk over the
contents being deleted.  I'm fairly sure that unmounting blocks on the
completion of that background process, which could take quite some
time in this case.
