Summary

Wire up OpenZFS with VOP_DEALLOCATE(9)

This will go to upstream actually. However a differential is created for
easier tools/tools/git/git-arc.sh workflow.

Does this comment need updating to instead say what FreeBSD does in this case?

sys/contrib/openzfs/module/os/freebsd/zfs/zfs_vnops_os.c

That seems necessary. I don't recall we have the same limitation like Solaris that VOP can only issued on opened files.

khng marked an inline comment as not done.

Removed SPACECTL_F_CANEXPAND support on SPACECTL_DEALLOC

Can't think of any use of it right now.

  • New zfs_deallocate and new DMU api instead of calling into zfs_freesp

_PC_FDEALLOC_PRESENT -> _PC_DEALLOC_PRESENT
