[PATCH 1/4] xfs: remove support for disabling quota accounting on a mounted file system

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Disabling quota accounting is hairy, racy code with all kinds of pitfalls.
And it has a very strange mind set, as quota accounting (unlike
enforcement) really is a property of the on-disk format.  There is no good
use case for supporting this.
