A new comer and learner.
During troubleshooting a system shutdown hang problem (not reproducible on lab, last log printing by kernel is Unmounting xxx, which is a fuse file system), we would like to add kernel logs in fuse in order to isolate the hang point (kernel, fuse or our fuse process).
The plan is to print kernel log on entry and exit of fuse_put_super. The questions are:
1. Is it a reasonable way to know that fuse get kernel request to shut down the file system and fuse get user space file system process response for the fuse destroy?
2. Is there any way to get the mount point at fuse_put_super, the input is super_block?
