Thank you for the patch. Compiling yields:
make targz-pkg block/genhd.c: In function `printk_all_partitions': block/genhd.c:240: Warnung: implicit declaration of function `mutex_lock' block/genhd.c:240: error: `block_subsys_lock' undeclared (first use in this function) block/genhd.c:240: error: (Each undeclared identifier is reported only once block/genhd.c:240: error: for each function it appears in.) block/genhd.c:273: Warnung: implicit declaration of function `mutex_unlock' make[3]: *** [block/genhd.o] Error 1 make[2]: *** [block] Error 2 make[1]: *** [targz-pkg] Error 2 make: *** [targz-pkg] Error 2
Can you please help me pointing to "mutex_lock" and "block_subsys_lock". Sorry.
Kind regards
Markus
