Subject: almost time to run my kernel source cleaning scripts again?
Date: Wed, 11 Apr 2012 17:07:31 -0400 (EDT) [thread overview]
Message-ID: <alpine.DEB.2.02.1204111700170.4733@oneiric> (raw)
it's been a while so i was thinking of firing up my scripts to
peruse the source tree looking for oddities/inconsistencies/whatever
(unless someone else is already doing that).
one example is looking for preprocessor tests of symbols that aren't
defined in any Kconfig file, and i can focus on any part of the source
tree. for example, if i run that script against drivers/mmc, i get:
>>>>> MMC_MSM7X00A_RESUME_IN_WQ
drivers/mmc/host/msm_sdcc.c:1408:#ifdef CONFIG_MMC_MSM7X00A_RESUME_IN_WQ
telling me that a source file is testing a CONFIG variable that
doesn't exist.
the scripts are available online (maybe i better test them first),
so anyone's free to run them against any part of the tree they want.
running this script against drivers/staging is always good for
entertainment:
>>>>> CAVIUM_OCTEON_NUM_PACKET_BUFFERS
drivers/staging/octeon/ethernet-defines.h:36: * CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS
drivers/staging/octeon/ethernet.c:56:#if defined(CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS) \
drivers/staging/octeon/ethernet.c:57: && CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS
drivers/staging/octeon/ethernet.c:58:int num_packet_buffers = CONFIG_CAVIUM_OCTEON_NUM_PACKET_BUFFERS;
>>>>> CONSOLE_115200
drivers/staging/serial/68360serial.c:310:#elif defined(CONFIG_CONSOLE_115200)
>>>>> CONSOLE_19200
drivers/staging/serial/68360serial.c:308:#elif defined(CONFIG_CONSOLE_19200)
>>>>> CONSOLE_9600
drivers/staging/serial/68360serial.c:306:#if defined(CONFIG_CONSOLE_9600)
>>>>> FORCE_HARD_FLOAT
drivers/staging/rtl8192u/r8192U_core.c:27:#ifndef CONFIG_FORCE_HARD_FLOAT
... lots more ...
i'll make sure the scripts work and maybe let them loose to find
stuff in a day or two.
