Hi,
I am exploring fs sysctl parameters and unable to find the reference to fs.quota.warnings parameter in the kernel source code. I tried searching with fs.quota.warnings (ignoring case) and also sysctl_fs_quota_warnings.
Could anyone please point me to the place in the kernel source where this parameter is used?
Look at the flag_print_warnings variable in fs/quota/dquot.c
Thank you. But how do I associate it with fs.quota.warnings? Asking because this would be useful for me to associate other sysctl parameters in future.
Step back a minute and think about how you create a sysctl entry. It's with a call to register_sysctl_table(), right? And what is the parameter of that function? It takes a table that describes the sysctl directory structure. And from that you can see the different quota sysctl entries and variables.
Look at the sys_table and fs_table structures for that information, understand how they work and then you will be able to find any sysctl entry in the kernel source quite easily.
hope this helps,
