With the new ordering in __dentry_kill() it has become redundant - it's set if and only if both DCACHE_DENTRY_KILLED and DCACHE_SHRINK_LIST are set. We set it in __dentry_kill(), after having set DCACHE_DENTRY_KILLED with the only condition being that DCACHE_SHRINK_LIST is there; all of that is done without dropping ->d_lock and the only place that checks that flag (shrink_dentry_list()) does so under ->d_lock, after having found the victim on its shrink list. Since DCACHE_SHRINK_LIST is set only when placing dentry into shrink list and removed only by shrink_dentry_list() itself, a check for DCACHE_DENTRY_KILLED in there would be equivalent to check for DCACHE_MAY_FREE.

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.
