One of the members is bool type and this causes sparse warnings. 16:1: warning: expression using sizeof bool 60:1: warning: expression using sizeof bool 16:1: warning: odd constant _Bool cast (ffffffffffffffff becomes 1) 60:1: warning: odd constant _Bool cast (ffffffffffffffff becomes 1) This commit suppresses the warnings, by changing type of the member to 'unsigned int'. Additionally, this commit applies '!!' idiom to get 0/1 from 'in_interrupt()'.
