Subject: lib/posix-process/signal: Add kernel definition of sigset_t
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=42798c043101db8f0d5950a8bac9ef00e06787cc;p=unikraft%2Funikraft.git

lib/posix-process/signal: Add kernel definition of sigset_t

POSIX specifies that sigset_t can be defined either as integer
type or a structure type. Add kernel definition of sigset_t to
avoid compilation errors caused by flavors of libc that use the
struct definition.
