Assuming that kprint_block_flush() is a combination of kprint_block_printit() and kprint_block_abort(), you coulld make a macro wrapper for this to preclude leaks:
#define KPRINT_BLOCK(block, level, code) \ do { \ struct kprint_block block; \ kprint_block_init(&block, KPRINT_##level); \ do { \ code ; \ kprint_block_printit(&block); \ while (0); \ kprint_block_abort(&block); \ } while(0)
The inner do { } while(0) region is so you can abort with "break".
(Or you can split it into KPRINT_BEGIN() and KPRINT_END() macros, if that works out to be cleaner.) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
