For debugging an umount failure in xfstests generic/043 generic/044 in some configurations, we needed more information on the shutdown ioctl which was suspected of being related to the cause, so tracepoints are added in this patch e.g. "trace-cmd record -e smb3_shutdown_enter -e smb3_shutdown_done -e smb3_shutdown_err" Sample output: godown-47084 [011] ..... 3313.756965: smb3_shutdown_enter: flags=0x1 tid=0x733b3e75 godown-47084 [011] ..... 3313.756968: smb3_shutdown_done: flags=0x1 tid=0x733b3e75 Tested-by: Anthony Nandaa (Microsoft) <profnandaa@gmail.com> Signed-off-by: Steve French <stfrench@microsoft.com>
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.
