Looking at this function definition:
static inline const char *str_plural(size_t num)
{
return num == 1 ? "" : "s";
}
It is wrong: num == 0 should not imply plural. This function needs to be fixed.
E.g. it should be:
static inline const char *str_plural(size_t num)
{
return num <= 1 ? "" : "s";
}
Please fix that first and then we can apply your patch to zonefs.
