Linux kernel source tree

David Howells <dhowells@redhat.com> says:
Here are some miscellaneous fixes and changes for netfslib and cifs, if you
could consider pulling them.
Many of these were found because a bug in Samba was causing smbd to crash
and restart after about 1-2s and this was vigorously and abruptly
exercising the netfslib retry paths.
Subsequent testing of the cifs RDMA support showed up some more bugs, but
the fixes for those went via the cifs tree and have been removed from this set
as they're now upstream.
First, there are some netfs fixes:
(1) Fix a hang due to missing case in final DIO read result collection
not breaking out of a loop if the request finished, but there were no
subrequests being processed and NETFS_RREQ_ALL_QUEUED wasn't yet set.
(2) Fix a double put of the netfs_io_request struct if completion happened
in the pause loop.
(3) Provide some helpers to abstract out NETFS_RREQ_IN_PROGRESS flag
wrangling.
(4) Fix infinite looping in netfs_wait_for_pause/request() which wa caused
by a loop waiting for NETFS_RREQ_ALL_QUEUED to get set - but which
wouldn't get set until the looping function returned. This uses patch
(3) above.
(5) Fix a ref leak on an extra subrequest inserted into a request's list
of subreqs because more subreq records were needed for retrying than
were needed for the original request (say, for instance, that the
amount of cifs credit available was reduced and, subsequently, the ops
had to be smaller).
Then a bunch of cifs fixes, some of which are from other people:
(6-8) cifs: Fix various RPC callbacks to set NETFS_SREQ_NEED_RETRY if a
subrequest fails retriably.
(10) Fix a warning in the workqueue code when reconnecting a channel.
Followed by some patches to deal with i_size handling:
(11) Fix the updating of i_size to use a lock to avoid a race between
testing if we should have extended the file with a DIO write and
changing i_size.
(12) A follow-up patch to (11) to merge the places in netfslib that update
i_size on write.
And finally a couple of patches to improve tracing output, but that should
otherwise not affect functionality:
(13) Renumber the NETFS_RREQ_* flags to make the hex values easier to
interpret by eye, including moving the main status flags down to the
lowest bits, with IN_PROGRESS in bit 0.
(14) Update the tracepoints in a number of ways, including adding more
tracepoints into the cifs read/write RPC callback so that differend
MID_RESPONSE_* values can be differentiated.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
