This doesn't look like it would actually work.
As I understand the timer usage, it should periodically send a signal. The timer code I posted really does this, at least when I take the timer_* functions "as it is" outside and test them, calling them in the same order as in the repair code. I tested that before sending the patch.
I have to try it in xfs_repair yet - this is limited by having small storage space for a filesystem, where the reporting interval would be noticeable. The best thing for this I have now is an old USB2 8 GB flash drive, filled with multiple copies of installed Debian. However, even on a raspberry pi, it still runs quickly. I guess few hundreds of GB would do it, but I need to dig out an old USB2-sata reduction somewhere and a HDD... (And I didn't noticed any difference in output.)
So in meantime, why do you think this won't work?
Cheers,
Jan
