  f2fs: keep inline_data when compression conversion (2020-04-03 10:21:32 -0700)

----------------------------------------------------------------
f2fs-for-5.7-rc1

In this round, we've mainly focused on fixing bugs and addressing issues in
recently introduced compression support.

Enhancement:
- add zstd support, and set LZ4 by default
- add ioctl() to show # of compressed blocks
- show mount time in debugfs
- replace rwsem with spinlock
- avoid lock contention in DIO reads

Some major bug fixes wrt compression:
- compressed block count
- memory access and leak
- remove obsolete fields
- flag controls

Other bug fixes and clean ups:
- fix overflow when handling .flags in inode_info
- fix SPO issue during resize FS flow
- fix compression with fsverity enabled
- potential deadlock when writing compressed pages
- show missing mount options
