[dm-devel] directio path-checker for multipath-tools

[christophe varoqui]

Sorry I didn't reply earlier.

Nice work.

+       buf = (unsigned char *)malloc(blksize + pgsize);
+       if (!buf){
+               goto out;
+       }

Don't you want to use an oversized buffer instead of malloc'ing in this
code path ?
