Summary:
Convert MAINTAINERS into a Github CODEOWNERS file. This will
automatically assign reviewers to some GH pull requests. The conversion
is not 1:1; some committers don't have Github accounts (e.g. adrian),
some functional areas don't neatly correspond to a set of files (e.g.
kqueue), and mailing lists can't be assigned as a reviewer (e.g.
secteam@). But it's a start.

Return EBUSY instead and let caller to handle the issue.
For vgone()/vnode reclamation, caller first does vinvalbuf(V_SAVE),
which return EBUSY in case dirty buffers where not flushed. Then caller
calls vinvalbuf(0) due to non-zero return, which gets rid of all dirty
buffers without dependencies.

Instead of requiring all implementations of vfs_quotactl to unbusy
the mount for Q_QUOTAON and Q_QUOTAOFF, add an "mp_busy" in/out param
to VFS_QUOTACTL(9). The implementation may then indicate to the caller
whether it needed to unbusy the mount.
Also, add stbool.h to libprocstat modules which #define _KERNEL
before including sys/mount.h. Otherwise they'll pull in sys/types.h
before defining _KERNEL and therefore won't have the bool definition
they need for mp_busy.

Parts of libprocstat like to pretend they're kernel components for the
sake of including mount.h, and including sys/types.h in the _KERNEL
case doesn't fix the build for some reason. Revert both the

Invalidate the last page of a demoted superpage mapping, instead of the
first page, as it results in slightly more promotions and fewer
failures. While here, replace 'boolean_t's with 'bool's in
mmu_radix_advise().
Simplify pmap_clear_modify() a bit, by assuming that since the superpage
demotion succeeded, all 4k mappings from it are valid. Deindent the
surrounding code, as there are no 'else' branches in the code anyway.
Changes since 1.25.0.0 are listed here. This list comes from the
Release Notes for the "Chelsio Unified Wire v3.14.0.3 for Linux"
release dated 2021-05-21.
Fixes
-----
BASE:
- Fixed Back to back T6 100G-CR4 link coming up with NO FEC sometimes.
- [T5] Try to bring up link in 1G speed if link doesn't come up on 10G.
- Fixed a bug to not allow BaseR fec in 100G speed.
- Fixed linkup issues on BT adapter in 1G and 100M speed.

version 0x80.
ETH:
- Fixed a case when firmware failed to deliver NIC WR completion to host.
- No rate limit support for WR ETH_TX_PKTS2 due to performance reasons.
OFLD
- Fixed a connection hang in SO adapters when tp_plen_max (set by driver)
is more than the window size.
- Added fw_filter_vnic_mode to firmware API file (t4fw_interface.h)
- Use correct rx channel in coprocessor crypto completion (CPL_FW6_PLD). This
was causing out of order completion to host.
FOiSCSI

- Fixed a crash during lun reset.
Enhancements
------------
ETH:
- Rate limiting support added for encapsulated (vxlan, nvgre, geneve) NIC TCP
packets.
OFLD:
- More than 128 SGLs supported in FW_RI_FR_NSMR_WR. Now, more than 16GB
(upto 64GB) of PBLs can be written with single FW_RI_FR_NSMR_WR.

Part of the nvme recovery process for errors is to reset the
card. Sometimes, this results in failing the entire controller. When nda
is in use, we free the sim, which will sleep until all the I/O has
completed. However, with only one thread, the request fail task never
runs once the reset thread sleeps here. Create two threads to allow I/O
to fail until it's all processed and the reset task can proceed.
This is a temporary kludge until I can work out questions that arose
during the review, not least is what was the race that queueing to a
failure task solved. The original commit is vague and other error paths
in the same context do a direct failure. I'll investigate that more
completely before committing changing that to a direct failure. mav@
raised this issue during the review, but didn't otherwise object.
Multiple threads, though, solve the problem in the mean time until other
such means can be perfected.

GitHub removed Clang 9 from the 20.04 image[1], breaking this build.
Thus, manually add the specific versioned packages we need for the
Ubuntu jobs to ensure they're installed. Note that we don't do the same
for macOS, as Homebrew does not allow multiple llvm@N to co-exist,
giving an error if you attempt to install a second one. In practice we
don't actually use the compiler field here for anything other than the
build name, it's only the cross-bindir that matters, so when it
eventually moves to 12 the name will get confusing but the job will
still work.

If an iSCSI connection is shutdown abruptly (e.g. by a RST from the
peer), pending iSCSI PDUs and page pod work requests can be in the
ulp_pduq when the final CPL is received indicating the death of the
connection.
Reported by: Jithesh Arakkan @ Chelsio
In 4427ac3675f9, the TOM driver stopped sending work requests to
program iSCSI page pods directly and instead queued them to be written
asynchronously with iSCSI PDUs. The queue of mbufs to send is
protected by the inp lock. However, the inp cannot be safely obtained
from the toep since a RST from the remote peer might have cleared
toep->inp asynchronously in an ithread. To fix, obtain the inp from
the socket as is already done in icl_cxgbei_conn_pdu_queue_cb() and
fail the new transfer setup with ECONNRESET if the connection has been
reset.
To avoid passing sockets or inps into the page pod routines, pull the
mbufq out of the two relevant page pod routines such that the routines
queue new work request mbufs to a caller-supplied mbufq.

T6 makes several changes relative to T5 for receive of iSCSI PDUs.
First, earlier adapters issue either 2 or 3 messages to the host for
each PDU received: CPL_ISCSI_HDR contains the BHS of the PDU,
CPL_ISCSI_DATA (when DDP is not used for zero-copy receive) contains
the PDU data as buffers on the freelist, and CPL_RX_ISCSI_DDP with
status of the PDU such as result of CRC checks. In T6, a new
CPL_RX_ISCSI_CMP combines CPL_ISCSI_HDR and CPL_RX_ISCSI_DDP. Data
PDUs which are directly placed via DDP only report a single
CPL_RX_ISCSI_CMP message. Data PDUs received on the free lists are
reported as CPL_ISCSI_DATA followed by CPL_RX_ISCSI_CMP. Control PDUs
such as R2T are still reported via CPL_ISCSI_HDR and CPL_RX_ISCSI_DDP.
Supporting this requires changing the CPL_ISCSI_DATA handler to
allocate a PDU structure if it is not preceded by a CPL_ISCSI_HDR as
well as support for the new CPL_RX_ISCSI_CMP.
Second, when using DDP for zero-copy receive, T6 will only issue a
CPL_RX_ISCSI_CMP after a burst of PDUs have been received (indicated
by the F flag in the BHS). In this case, the CPL_RX_ISCSI_CMP can
reflect the completion of multiple PDUs and the BHS and TCP sequence
number included in the message are from the last PDU received in the
burst. Notably, the message does not include any information about
earlier PDUs received as part of the burst. Instead, the driver must
track the amount of data already received for a given transfer and use
this to compute the amount of data received in a burst. In addition,
the iSCSI layer currently has no way to permit receiving a logical PDU
which spans multiple PDUs. Instead, the driver presents each burst as
a single, "large" PDU to the iSCSI target and initiators. This is
done by rewriting the buffer offset and data length fields in the BHS
of the final PDU as well as rewriting the DataSN so that the received
PDUs appear to be in order.
To track all this, cxgbei maintains a hash table of 'cxgbei_cmp'
structures indexed by transfer tags for each offloaded iSCSI
connection. When a SCSI_DATA_IN message is received, the ITT from the
received BHS is used to find the necessary state in the hash table,
whereas SCSI_DATA_OUT replies use the TTT as the key. The structure
tracks the expected starting offset and DataSN of the next burst as
well as the rewritten DataSN value used for the previously received
PDU.

The generated C output for aicasm_scan.l defines yylineno already, so
references to it from other files should use an extern declaration.
The STAILQ_HEAD use in aicasm_symbol.h also provided an identifier,
causing it to both define the struct type and define a variable of that
struct type, causing any C file including the header to define the same
variable. This variable is not used (and confusingly clashes with a
field name just below) and was likely caused by confusion when switching
between defining fields using similar type macros and defining the type
itself.
