Among the flags in scan_control: 1. sc->may_swap, which indicates swap constraint due to memsw.max, is supported as usual. 2. sc->proactive, which indicates reclaim by memory.reclaim, may not opportunistically skip the aging path, since it is considered less latency sensitive. 3. !(sc->gfp_mask & __GFP_IO), which indicates IO constraint, lowers swappiness to prioritize file LRU, since clean file folios are more likely to exist. 4. sc->may_writepage and sc->may_unmap, which indicates opportunistic reclaim, are rejected, since unmapped clean folios are already prioritized. Scanning for more of them is likely futile and can cause high reclaim latency when there is a large number of memcgs. The rest are handled by the existing code.

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.
