Hi! I've seen sqlite3 crap out due to "disk IO error". It looks like the F_SETFL path is returning EDEADLK when it shouldn't be - only the "wait" version of this should be.
The kernel code looks to be: lf_setlock() -> lf_add_outgoing() -> lf_add_edge() -> graph_add_edge() -> EDEADLK .. and lf_setlock() will return an error from lf_add_outgoing() without checking if it's (a) EDEADLK, and (b) whether we're going to sleep or not. So, sqlite3 trips up on this. I'm sure other things do. What should the correct thing be? It looks like EWOULDBLOCK is the correct value to return for F_SETFL failing, not EDEADLK. What do those-who-know-POSIX-standards-better-than-I think?
