Subject: include/linux/huge_mm.h: return NULL instead of false for pmd_trans_huge_lock()
X-Git-Tag: v4.6-rc2~12^2~8
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=969e8d7e47f93ef693028667480558de8f70523f;p=linux.git

include/linux/huge_mm.h: return NULL instead of false for pmd_trans_huge_lock()

The return value of pmd_trans_huge_lock() is a pointer, not a boolean
value, so use NULL instead of false as the return value.
