Junxiao Bi 4d985f41d9 ocfs2: fix value of OCFS2_INVALID_SLOT 
commit 9277f8334f upstream.

In the ocfs2 disk layout, slot number is 16 bits, but in ocfs2
implementation, slot number is 32 bits.  Usually this will not cause any
issue, because slot number is converted from u16 to u32, but
OCFS2_INVALID_SLOT was defined as -1, when an invalid slot number from
disk was obtained, its value was (u16)-1, and it was converted to u32.
Then the following checking in get_local_system_inode will be always
skipped:

 static struct inode **get_local_system_inode(struct ocfs2_super *osb,
                                               int type,
                                               u32 slot)
 {
 	BUG_ON(slot == OCFS2_INVALID_SLOT);
	...
 }

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
