[Linux-kernel-mentees] [PATCH v4 0/3] lspci: Update verbose help and show_range()

[Linux-kernel-mentees] [PATCH v4 0/3] lspci: Update verbose help and show_range()

[skunberg.kelsey]

Changes since v1:
  - Expand changes into more patches for easier review.
  - Combine three patches for lspci.c into patchset.

  * Patch 1: lspci: Include -vvv option in help
    No changes made. Added to series for review.

  * Patch 2: lspci: Remove unnecessary !verbose check in show_range()
    Move into it's own patch since v1. Dead code which checks for
    verbosity to be true.

  * Patch 3: lspci: Replace output for bridge with empty range from
    "None" to "[empty]"
    Patch builds off Patch 2 to change show_range() output to be more
    consistent between each level of verbosity.

Changes since v2:
  * Patch 1: Update commit log to imperative mood

  * Patch 2: Fix logical error
        Previous:
        (base > limit || verbose < 3)
        New:
        (base > limit && verbose < 3)

  * Patch 3: Fix logical error
        Previous:
        base > limit
        New:
        base <= limit

Changes since v3:
  * Patch 1 and 2: No change
  * Patch 3: Change output from "[empty]" to "[disabled]"

[Linux-kernel-mentees] [PATCH v4 2/3] lspci: Remove unnecessary !verbose check in show_range()

[skunberg.kelsey]

Remove 'if (!verbose)' code in show_range() due to not being called.
show_range() will only be called when verbose is true. Additional call
to check for verbosity within show_range() is dead code.

!verbose was used so nothing would print if the range behind a bridge
had a base > limit and verbose == false. Since show_range() will not be
called when verbose == false, not printing bridge information is
still accomplished.

[Linux-kernel-mentees] [PATCH v4 3/3] lspci: Change output for bridge with empty range to "[disabled]"

[skunberg.kelsey]

Change output displayed for memory behind bridge when the range is
empty to be consistent between each verbosity level. Replace "None" and
"[empty]" with "[disabled]". Old and new output examples listed below
for each verbosity level.

Show_range() is not called unless verbose == true. No output given
unless a verbose argument is provided.

OLD output for -v and -vv which uses "None" and -vvv uses "[empty]":

  Memory behind bridge: None                          # lspci -v
  Memory behind bridge: None                          # lspci -vv
  Memory behind bridge: 0000e000-0000efff [empty]     # lspci -vvv

NEW output for -v, -vv, and -vvv to use "[disabled]":

  Memory behind bridge: [disabled]                       # lspci -v
  Memory behind bridge: [disabled]                       # lspci -vv
  Memory behind bridge: 0000e000-0000efff [disabled]     # lspci -vvv

Advantage is consistent output regardless of verbosity level chosen and
to simplify the code.
