Theodore Ts'o 2e636c0c93 ext4: add EA_INODE checking to ext4_iget()
commit b3e6bcb94590dea45396b9481e47b809b1be4afa upstream.

Add a new flag, EXT4_IGET_EA_INODE which indicates whether the inode
is expected to have the EA_INODE flag or not.  If the flag is not
set/clear as expected, then fail the iget() operation and mark the
file system as corrupted.

This commit also makes the ext4_iget() always perform the
is_bad_inode() check even when the inode is already inode cache.  This
allows us to remove the is_bad_inode() check from the callers of
ext4_iget() in the ea_inode code.

README

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.
