Ka Ho Ng 0dc332bff2 Add fspacectl(2), vn_deallocate(9) and VOP_DEALLOCATE(9). ... fspacectl(2) is a system call to provide space management support to userspace applications. VOP_DEALLOCATE(9) is a VOP call to perform the deallocation. vn_deallocate(9) is a public KPI for kmods' use. The purpose of proposing a new system call, a KPI and a VOP call is to allow bhyve or other hypervisor monitors to emulate the behavior of SCSI UNMAP/NVMe DEALLOCATE on a plain file. fspacectl(2) comprises of cmd and flags parameters to specify the space management operation to be performed. Currently cmd has to be SPACECTL_DEALLOC, and flags has to be 0. fo_fspacectl is added to fileops. VOP_DEALLOCATE(9) is added as a new VOP call. A trivial implementation of VOP_DEALLOCATE(9) is provided. Sponsored by: The FreeBSD Foundation Reviewed by: kib Differential Revision: https://reviews.freebsd.org/D28347		2021-08-05 23:20:42 +08:00
