The CephFS kernel client does not enforce quotas set in a directory that isn't visible from the mount point. For example, given the path '/dir1/dir2', if quotas are set in 'dir1' and the filesystem is mounted with mount -t ceph <server>:<port>:/dir1/ /mnt then the client won't be able to access 'dir1' inode, even if 'dir2' belongs to a quota realm that points to it. This patch fixes this issue by simply doing an MDS LOOKUPINO operation for unknown inodes. Any inode reference obtained this way will be added to a list in ceph_mds_client, and will only be released when the filesystem is umounted.

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.
