Hello all, I hope this is the proper group. Here's where I need direction. I want to write a new "fuser", which makes direct kernel table calls, rather than what the current "fuser" does, which seems to be a file-tree-walk on /proc. We've found that on a heavily loaded system, the current "fuser" is far too slow and can actually have a serious performance impact. Here's my ideas sofar. Loop through the kernel task list, and for each task, lookup its file information. For each file structure, do a string compare with the desired file name. If a match, then print to stdout, the PID. While I have coded in C, I have extremely limited experience with the Linux kernel and I have no idea where to start. If pointed in a general direction, I should be able to ask more informed questions. At this point, I don't know what libraries to include, what kernel structures to access or how to access them.
