Subject: compile warning on master


When compiling with LLVM, it generates the following warning in
debugfs::do_lsdel():

367 debugfs/lsdel.c:155 col 23: warning: '&&' within '||'
[-Wlogical-op-parentheses]
368:                if (lsd.free_blocks && !lsd.bad_blocks ||
369:                    ~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~ ~~
370 debugfs/lsdel.c:155 col 23: note: place parentheses around the '&&'
expression to silence this warning
371:                if (lsd.free_blocks && !lsd.bad_blocks ||
372:                                    ^
373:                    (                                 )


Unfortunately, even looking at this code and the patch that changed it,
I can't figure out what the correct parenthesis is for it.

Zheng, could you please send a patch to fix this?

Cheers, Andreas
