Subject: mm: fix noisy sparse warning in LIBCFS_ALLOC_PRE()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=543dfb2df8ebb3eb0b499eae1d63de1701a99b40;p=linux-beck.git

mm: fix noisy sparse warning in LIBCFS_ALLOC_PRE()

Running sparse on drivers/staging/lustre results in dozens of warnings:
include/linux/gfp.h:281:41: warning: odd constant _Bool cast (400000
becomes 1)

Use "!!" to explicitly convert to bool and get rid of the warning.
