Subject: perf tools: /proc/modules names don't always match its name
X-Git-Tag: v2.6.33-rc1~399^2~1^2~30
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a2a99e8e12798706ec1026e5d8fc36f7c86122ce;p=pandora-kernel.git

perf tools: /proc/modules names don't always match its name

$ cut -d' ' -f1 /proc/modules|grep _|wc -l
 29
 $ cut -d' ' -f1 /proc/modules|grep _|sed 's/$/.ko'/g|while read n;do find /lib/modules/`uname -r` -name $n;done|wc -l
 12

For instance:

 $ grep ^aes_x86 /proc/modules
 aes_x86_64 9056 2 - Live 0xffffffffa0091000
 $ l /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko
 -rw-r--r-- 1 root root 136438 2009-09-22 19:05 /lib/modules/2.6.31-tip/kernel/arch/x86/crypto/aes-x86_64.ko

Handle that by introducing a strxfrchar routine that replaces
dashes with underscores when matching file names to loaded modules.
