When fscrypt is enabled we will align the truncate size up to the CEPH_FSCRYPT_BLOCK_SIZE always, so if we truncate the size in the same block more than once, the latter ones will be skipped being invalidated from the page caches. This will force invalidating the page caches by using the smaller size than the real file size. At the same time add more debug log and fix the debug log for truncate 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.
