Spl's debugging and assertion macros macro used the typical do/while(0) form for if/else friendliness, however, this limits their use in contexts where a do loop is not valid; such as within another multi-statement style macro. The following macros have been converted to not use do/while(0): PANIC, ASSERT, ASSERTF, VERIFY, VERIFY3_IMPL PANIC has been converted to a wrapper around the new spl_PANIC() function. The other macros have been converted to use the "&&" operator for the branch-predicition conditional and also to use spl_PANIC(). The __ASSERT() macro was not touched. It is only used by the debugging infrastructure and that code, including this macro, will be retired when the tracepoint patches are merged.
