Subject: include: Include <unistd.h> in pidfd-utils.h for syscall()
X-Git-Tag: v2.42-start~444^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=10add327c608b11b3d70215048aade4d1797b1fd;p=thirdparty%2Futil-linux.git

include: Include <unistd.h> in pidfd-utils.h for syscall()

In Glibc, <sys/syscall.h> only contains SYS_* macros and the syscall()
function is in <unistd.h>.  So include it.
