The format specifier in fprintf is "%u", that "%u" should use unsigned int type instead.the problem is discovered by reading code.
Signed-off-by: Zhu Jun zhujun2@cmss.chinamobile.com --- v1->v2: modify commit info add how to find the problem in the log v2->v3: Seems this can use macro WTERMSIG like those above usage, rather than changing the print format. v3->v4: Now the commit summary doesn't match the change you are making. Also WTERMSIG() is incorrect for this conditional code path. See comments below in the code path.
I would leave the v2 code intact. How are you testing this change? Please include the details in the change log. v4->v5: Compile the kernel for testing using make
