* bitstring(3): Add bitstring traversal macros.Vladimir Kondratyev2021-08-161-0/+207
| | | | | | | | | | | | | | | | The macro bit_foreach() traverses all set bits in the bitstring in the forward direction, assigning each location in turn to variable. The macro bit_foreach_at() traverses all set bits in the bitstring in the forward direction at or after the zero-based bit index, assigning each location in turn to variable. The bit_foreach_unset() and bit_foreach_unset_at() macros which traverses unset bits are implemented for completeness.

* uipc_shm: Implements fspacectl(2) supportKa Ho Ng2021-08-121-0/+199
| | | | | | | | | | | | | | This implements fspacectl(2) support on shared memory objects. The semantic of SPACECTL_DEALLOC is equivalent to clearing the backing store and free the pages within the affected range. If the call succeeds, subsequent reads on the affected range return all zero. tests/sys/posixshm/posixshm_tests.c is expanded to include a fspacectl(2) functional test.

* Add fspacectl(2), vn_deallocate(9) and VOP_DEALLOCATE(9).Ka Ho Ng2021-08-052-0/+339
| | | | | | | | | | | | | | | | | | | | | | 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

* fusefs: ensure that FUSE ops' headers' unique values are actually uniqueAlan Somers2021-06-192-0/+12
| | | | | | | | | | | | | | | | | Every FUSE operation has a unique value in its header. As the name implies, these values are supposed to be unique among all outstanding operations. And since FUSE_INTERRUPT is asynchronous and racy, it is desirable that the unique values be unique among all operations that are "close in time". Ensure that they are actually unique by incrementing them whenever we reuse a fuse_dispatcher object, for example during fsync, write, and listextattr.
