Eric Biggers 197cd89a43 f2fs: don't return vmalloc() memory from f2fs_kmalloc()
kmalloc() returns kmalloc'ed memory, and kvmalloc() returns either
kmalloc'ed or vmalloc'ed memory.  But the f2fs wrappers, f2fs_kmalloc()
and f2fs_kvmalloc(), both return both kinds of memory.

It's redundant to have two functions that do the same thing, and also
breaking the standard naming convention is causing bugs since people
assume it's safe to kfree() memory allocated by f2fs_kmalloc().  See
e.g. the various allocations in fs/f2fs/compress.c.

Fix this by making f2fs_kmalloc() just use kmalloc().  And to avoid
re-introducing the allocation failures that the vmalloc fallback was
intended to fix, convert the largest allocations to use f2fs_kvmalloc().

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.
