We want the snapdir to mirror the non-snapped directory's attributes for most things, but i_snap_caps represents the caps granted on the snapshot directory by the MDS itself. A misbehaving MDS could issue different caps for the snapdir and we lose them here. Only reset i_snap_caps when the inode is I_NEW. Also, move the setting of i_op and i_fop inside the if block since they should never change anyway.

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.
