It allows to reduce code duplication in differerent backends by accounting DMA time in common code. - Add to ctl_datamove_done() and be_move_done() callback samethr argument, reporting whether the callback is called in the same context as ctl_datamove(). It allows for some cases like iSCSI write with immediate data or camsim frontend write save one context switch, since we know that the context is sleepable. - Remove data_move_done() methods from struct ctl_backend_driver, unused since forever.

Added that to not leak resources. 2020-07-29T14:30:42Z Mark Johnston markj@FreeBSD.org 2020-07-29T14:30:42Z urn:sha1:59e0a2b84ae270c00ca27b141615e994977a293a usb(4): Stop checking for failures from malloc(M_WAITOK). 2018-01-24T17:04:01Z Edward Tomasz Napierala trasz@FreeBSD.org 2018-01-24T17:04:01Z urn:sha1:28f3d8b2c2999bbf1ba18565576395127b0c226e MFC after: 2 weeks 2017-12-25T04:48:39Z Alexander Kabaev kan@FreeBSD.org 2017-12-25T04:48:39Z urn:sha1:151ba7933aab5c8edc094715bffd9b97d84d2407 This reduces noise when kernel is compiled by newer GCC versions, such as one used by external toolchain ports.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. 2017-02-26T06:25:55Z Alexander Motin mav@FreeBSD.org 2017-02-26T06:25:55Z urn:sha1:789f39c3dcdce61273e16a305c5f82d101a2e823 This change removes limitation of single S/G list entry and limitation on maximal I/O size, using multiple data transfers per I/O if needed. Also it removes code duplication between send and receive paths, which are now completely equal. 2017-02-25T14:24:29Z Alexander Motin mav@FreeBSD.org 2017-02-25T14:24:29Z urn:sha1:ebaf2c29d762a723658b9e5f873bd6a7d0e1f2a8 USB MS BBB transport does not support autosense, so we have to queue any sense data back to CTL for later fetching via REQUEST SENSE. 2017-02-25T12:11:07Z Alexander Motin mav@FreeBSD.org 2017-02-25T12:11:07Z urn:sha1:5e70e673d9a19866edf8f9a18d17cddfb49b2eca This now mandatory for correct operation.
