Re: [Qemu-devel] [PATCH] qga: ignore EBUSY when freezing a filesystem

[Christian Theune]

Hi,

to clarify: I guess you ask about what happens when you thaw with the same 
condition: a filesystem that is mounted multiple times.

When I created the patch initially I looked at the thaw code and found it to 
already expect that thaws may happen outside its control and that the error 
handling is fine.

The code definitely does not have an early exit upon encountering an issue with 
thawing/double thawing.
