We only had dynamic tracepoints on errors in flush and close, but may be helpful to trace enter and non-error exits for those. Sample trace examples (excerpts) from "cp" and "dd" show two of the new tracepoints. cp-22823 [002] .... 123439.179701: smb3_enter: _cifsFileInfo_put: xid=10 cp-22823 [002] .... 123439.179705: smb3_close_enter: xid=10 sid=0x98871327 tid=0xfcd585ff fid=0xc7f84682 cp-22823 [002] .... 123439.179711: smb3_cmd_enter: sid=0x98871327 tid=0xfcd585ff cmd=6 mid=43 cp-22823 [002] .... 123439.180175: smb3_cmd_done: sid=0x98871327 tid=0xfcd585ff cmd=6 mid=43 cp-22823 [002] .... 123439.180179: smb3_close_done: xid=10 sid=0x98871327 tid=0xfcd585ff fid=0xc7f84682 dd-22981 [003] .... 123696.946011: smb3_flush_enter: xid=24 sid=0x98871327 tid=0xfcd585ff fid=0x1917736f dd-22981 [003] .... 123696.946013: smb3_cmd_enter: sid=0x98871327 tid=0xfcd585ff cmd=7 mid=123 dd-22981 [003] .... 123696.956639: smb3_cmd_done: sid=0x98871327 tid=0x0 cmd=7 mid=123 dd-22981 [003] .... 123696.956644: smb3_flush_done: xid=24 sid=0x98871327 tid=0xfcd585ff fid=0x1917736f Signed-off-by: Steve French <stfrench@microsoft.com> Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.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 Restructured Text 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.
