Another round of various bug fixes came in. Damien improved SMR drive support a
bit, and Chao replaced BUG_ON() with reporting errors to user since we've not
hit from users but did hit from crafted images. We've found a disk layout bug
in large_nat_bits feature which supports very large NAT entries enabled at mkfs.
If the feature is enabled, it will give a notice to run fsck to correct the
on-disk layout.
Enhancement:
- reduce memory consumption for SMR drive
- better discard handling for multiple partitions
- tracepoints for f2fs_file_write_iter/f2fs_filemap_fault
- allow to change CP_CHKSUM_OFFSET
- detect wrong layout of large_nat_bitmap feature
- enhance checking valid data indices
Bug fix:
- Multiple partition support for SMR drive
- deadlock problem in f2fs_balance_fs_bg
- add boundary checks to fix abnormal behaviors on fuzzed images
- inline_xattr space calculations
- replace f2fs_bug_on with errors
In addition, this series contains various memory boundary check and sanity check
of on-disk consistency.

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.
