Hi Om,
Please do mention the kernel version when you are referring to a problem. Because structures might have changed accordingly.
Yes. Now onwards I will. operator -> solved it. thanks, Om.
Hi, Trying out systemtap. Running into this problem.
--script begin-- [om@testserv ~]$ cat /space/stap/inode-watch.stp # Usage: # taps the vfs_write and vfs_read #
probe kernel.function ("vfs_read"), kernel.function("vfs_write") { inode = $file->f_dentry->d_inode->i_ino dev_nr = $file->f_dentry->d_inode->i_sb->s_dev
} -- script end--
I know why the error occur. From include/linux/fs.h, #define f_dentry f_path.dentry
Apparently f_dentry cannot be used from systemtap.
If I replace f_dentry with fpath.dentry, systemtap complains about string operations because `.` is string concatenation operator.
Any idea? Any pointers?
Try f_path->dentry.
"." in stap language is a concatenation operator.

Thanks and Regards
