Re: [PATCH] gpu: Consistently use octal not symbolic permissions

From: Christian KÃnig
Date: Fri May 25 2018 - 07:59:49 EST

Well I think we rejected that multiple times now.

At least I find the symbolic permissions easier to read and I absolutely don't see any reason why we should only use one form.

Christian.

There is currently a mixture of octal and symbolic permissions uses
in files in drivers/gpu/drm and one file in drivers/gpu.

There are ~270 existing octal uses and ~115 S_<FOO> uses.

Convert all the S_<FOO> symbolic permissions to their octal equivalents
as using octal and not symbolic permissions is preferred by many as more
readable.

see: https://lkml.org/lkml/2016/8/2/1945

Done with automated conversion via:
$ ./scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace <files...>

Miscellanea:

o Wrapped modified multi-line calls to a single line where appropriate
o Realign modified multi-line calls to open parenthesis
o drivers/gpu/drm/msm/adreno/a5xx_debugfs.c has a world-writeable
debug permission for "reset" - perhaps that should be modified
