Subject: btrfs: tests: polish ifdefs around testing helper
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b2fa11547bc1693a8dd8e7379dd4e43d31f49c50;p=openwrt%2Fstaging%2Fblogic.git

btrfs: tests: polish ifdefs around testing helper

Avoid the inline ifdefs and use two sections for self-tests enabled and
disabled.

Though there could be no ifdef and unconditional test_bit of
BTRFS_FS_STATE_DUMMY_FS_INFO, the static inline can help to optimize out
any code that would depend on conditions using btrfs_is_testing.

As this is only for the testing code, drop unlikely().
