X-Git-Tag: v2.6.17-rc1~930
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7b5b9ef0e17d52c188fe73ea78e884fe67079e6c;p=linux-2.6

[PATCH] cpuset cleanup not not operators

Since the test_bit() bit operator is boolean (return 0 or 1), the double not
"!!" operations needed to convert a scalar (zero or not zero) to a boolean are
not needed.
