Linus Torvalds 1501f707d2 f2fs-for-5.19

In this round, we've refactored the existing atomic write support implemented
 by in-memory operations to have storing data in disk temporarily, which can give
 us a benefit to accept more atomic writes. At the same time, we removed the
 existing volatile write support. We've also revisited the file pinning and GC
 flows and found some corner cases which contributeed abnormal system behaviours.
 As usual, there're several minor code refactoring for readability, sanity check,
 and clean ups.
 
 Enhancement
  - allow compression for mmap files in compress_mode=user
  - kill volatile write support
  - change the current atomic write way
  - give priority to select unpinned section for foreground GC
  - introduce data read/write showing path info
  - remove unnecessary f2fs_lock_op in f2fs_new_inode
 
 Bug fix
  - fix the file pinning flow during checkpoint=disable and GCs
  - fix foreground and background GCs to select the right victims and get free
    sections on time
  - fix GC flags on defragmenting pages
  - avoid an infinite loop to flush node pages
  - fix fallocate to use file_modified to update permissions consistently
