  f2fs: fix to do sanity check on direct node in truncate_dnode() (2023-06-30 16:38:27 -0700)

----------------------------------------------------------------
f2fs update for 6.5-rc1

In this cycle, we've mainly investigated the zoned block device support along
with patches such as correcting write pointers between f2fs and storage, adding
asynchronous zone reset flow, and managing the number of open zones. Other than
them, f2fs adds another mount option, "errors=x" to specify how to handle when
it detects an unexpected behavior at runtime.

Enhancement:
 - support errors=remount-ro|continue|panic mountoption
 - enforce some inode flag policies
 - allow .tmp compression given extensions
 - add some ioctls to manage the f2fs compression
 - improve looped node chain flow
 - avoid issuing small-sized discard commands during checkpoint
 - implement an asynchronous zone reset

Bug fix:
 - fix deadlock in xattr and inode page lock
 - fix and add sanity check in some error paths
 - fix to avoid NULL pointer dereference f2fs_write_end_io() along with put_super
 - set proper flags to quota files
 - fix potential deadlock due to unpaired node_write lock use
 - fix over-estimating free section during FG GC
 - fix the wrong condition to determine atomic context

As usual, also there are a number of patches having code refactoring and minor
clean-ups.
