  f2fs: fix to avoid accessing xattr across the boundary (2019-05-09 09:43:29 -0700)

----------------------------------------------------------------
f2fs-for-5.2-rc1

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.
