Linux kernel source tree
afc5b36e29
When ATTR_ATIME_SET and ATTR_MTIME_SET are set in the ia_valid mask, the notify_change() logic takes that to mean that the request should set those values explicitly, and not override them with "now". With the advent of delegated timestamps, similar functionality is needed for the ctime. Add a ATTR_CTIME_SET flag, and use that to indicate that the ctime should be accepted as-is. Also, clean up the if statements to eliminate the extra negatives. In setattr_copy() and setattr_copy_mgtime() use inode_set_ctime_deleg() when ATTR_CTIME_SET is set, instead of basing the decision on ATTR_DELEG.

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.
