[PATCH] mm/hmm/test: Fix an error code in dmirror_allocate_chunk()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is supposed to return false on failure, not a negative error code.

Fixes: 170e38548b81 ("mm/hmm/test: use after free in dmirror_allocate_chunk()")

I messed this up earlier...  My devel version of Smatch prints too much
garbage so I missed the warning when I first wrote the patch.  :/
Sorry.
