Prior to commit7c03e2cda4("vfs: move cap_convert_nscap() call into vfs_setxattr()") the translation of nscap->rootid did not take stacked filesystems (overlayfs and ecryptfs) into account. That patch fixed the overlay case, but made the ecryptfs case worse. Restore old the behavior for ecryptfs that existed before the overlayfs fix. This does not fix ecryptfs's handling of complex user namespace setups, but it does make sure existing setups don't regress. Reported-by: Eric W.

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.
