Kemeng Shi 778b1ac4d6 ext4: try all groups in ext4_mb_new_blocks_simple [ Upstream commit `19a043bb1f` ] ext4_mb_new_blocks_simple ignores the group before goal, so it will fail if free blocks reside in group before goal. Try all groups to avoid unexpected failure. Search finishes either if any free block is found or if no available blocks are found. Simpliy check "i >= max" to distinguish the above cases.

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.
