FP_MAX_ENTRY_COUNT

#define FP_MAX_ENTRY_COUNT   20

Don't allow more than this many entries in a fail point set by sysctl. The 99.99...% case is to have 1 entry. I can't imagine having this many entries, so it should not limit us. Saves on re-mallocs while holding a non-sleepable lock.

fail_point_eval_nontrivial()

enum fail_point_return_code fail_point_eval_nontrivial	(	struct fail_point *	fp,
		int *	return_value
	)

This does the real work of evaluating a fail point. If the fail point tells us to return a value, this function returns 1 and fills in 'return_value' (return_value is allowed to be null). If the fail point tells us to panic, we never return. Otherwise we just return 0 after doing some work, which means "keep going".

Pausing is inherently strange with multiple entries given our design. That is because some entries could be unreachable, for instance in cases like: pause->return. We can never reach the return entry. The sysctl layer actually truncates all entries after a pause for this reason.

We will transfer the entries to free to fp_ents_free_list while holding the spin mutex, then free it after we drop the lock. This avoids triggering witness due to sleepable mutexes in the memory allocator.

Set an internal fail_point structure from a human-readable failpoint string in a lock-safe manner.

ref protects our new malloc'd stuff from being garbage collected before we link it.

Transfer the entries we are going to keep to a new list. Get rid of useless zero probability entries, and entries with hit count 0. If 'off' is present, and it has no hit count set, then all entries after it are discarded since they are unreachable.

If this fail point is annotated as being in a non-sleepable ctx, convert sleep to delay and convert the msec argument to usecs.
