Subject: [PATCH RFC 00/13] Simplify the print format string with new '%pD'

This is the followup work after changing the behavior of '%pD' to
print the full path of file.

Background
==========
Linus suggested printing the full path of file instead of printing
the components as '%pd'.

This series is based on my patch series of making '%pD' print the full
path of file [1], which is stable now.

Test
====
I only tested it with basic compilation and booting. All the changed
codes are compiled and built successfully on Arm64. Therefore set it as
RFC.

Patch details
=============
Patches 01 to 06 with minor changes are easy for review. They are to
remove the hard coding and the postfix number of previous '%pD'. This
should be removed after the '%pD' behavior is changed.

Patches 07 to 13 are changed to simplify the printing helpers.

Jia He (13):
  s390/hmcdrv: remove the redundant directory path in format string
  afs: Remove the number postfix of '%pD' in format string
  fs: Remove the number postfix of '%pD' in format string
  NFS: Remove the number postfix of '%pD' in format string
  NFSD: Remove the number postfix of '%pD' in format string
  ovl: remove the number postfix of '%pD' in format string
  iomap: simplify iomap_swapfile_fail() with '%pD' specifier
  fs/coredump: simplify the printing with '%pD' and '%pd' specifier
  mm/filemap: simplify the printing with '%pD' specifier
  usb: gadget: simplify the printing with '%pD' specifier
  md/bitmap: simplify the printing with '%pD' specifier
  mm: simplify the printing with '%pd' specifier
  ext4: simplify the printing with '%pD' specifier
