Great. BTW, is the number of forgets consistent with the number of touched files?
If the latter would be significantly larger, it could mean that the kernel decided not to forget some inodes, for whatever reason.
Hmmm. The calls to forget could be also made after the umount request. The solution would be to log each forget() with its time stamp. I know, this means flooding the logfile, but for a test, we could live with it.
But maybe not needed. I remember running glusterfs under valgrind and there were lots of still allocated memory before exiting.
So fuse_forget() does not forget?
Just thinking.
