let have a dependant link: REQ -> LINK_TIMEOUT -> LINK_TIMEOUT 1. submission stage: submission references for REQ and LINK_TIMEOUT are dropped. So, references respectively (1,1,2) 2. io_put(REQ) + FAIL_LINKS stage: calls io_fail_links(), which for all linked timeouts will call cancel_timeout() and drop 1 reference. So, references after: (0,0,1). That's a leak. Make it treat only the first linked timeout as such, and pass others through __io_double_put_req().

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.
