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

From: Jia He
Date: Wed Jul 14 2021 - 23:16:00 EST


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.

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
