[systemd-devel] [PATCH] util: arg 'nbytes' of loop_read/write should be of type ssize_t

[fykcee1 at gmail.com]

Hi all,

loop_read/write will try to fill/read 'nbytes' of caller supplying buffer.
This argument is currently of type size_t, which is always true
for loop quit condition "while (nbytes > 0)", hence we change it to
type ssize_t here. This also helps to detect passed-in 'nbytes' of value -1
for example.
