Hello list,
just wanted to report that my ENOSPC errors are gone. Thanks to wang for
his great patches.
but the space_info corruption still occours.
On every umount i see:
[93022.166222] BTRFS: space_info 4 has 208952672256 free, is not full
[93022.166224] BTRFS: space_info total=363998478336, used=155045216256,
pinned=0, reserved=0, may_use=524288, readonly=65536
Greets,
Stefan
