Implemented -e trace=%statfs option. It groups statfs+statfs64+ustat
Below is patch attached. Please review.
From 38ea98c7ba87bc485d8af34fc401f46b05b2c035 Mon Sep 17 00:00:00 2001
From: Abhishek Tiwari <erabhishektiwar...@gmail.com>
Date: Thu, 16 Mar 2017 16:55:44 +0530
Subject: [PATCH v4] Implement -e trace=%statfs option for tracing statfs like syscalls.
linux/*/syscallent.h part is modified automatically by:
git grep -Fl 'statfs' linux/*/syscallent* | xargs sed -i 's/TD\(,[[:space:]]*SEN(statfs\)/TD|SFS\1/'
git grep -Fl 'statfs' linux/*/syscallent* | xargs sed -i 's/TF\(,[[:space:]]*SEN(statfs\)/TF|SFS\1/'
git grep -Fl 'statfs' linux/*/syscallent* | xargs sed -i 's/0\(,[[:space:]]*SEN(osf_statfs\)/SFS\1/'
git grep -Fl 'statfs' linux/*/syscallent* | xargs sed -i 's/0\(,[[:space:]]*SEN(.*_statfs\)/SFS\1/'
git grep -Fl 'ustat' linux/*/syscallent* | xargs sed -i 's/0\(,[[:space:]]*SEN(.*_ustat\)/SFS\1/'
