Subject: exportfs: Add a common exit label in exportfs()
X-Git-Tag: nfs-utils-1-2-3-rc4~7
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=3ca5879be32c4c11750e12230ff588195fff0738

exportfs: Add a common exit label in exportfs()

Clean up: Reduce code duplication by introducing a goto label for
freeing hp and exiting.  This will make replacing "struct hostent *"
with "struct addrinfo *" more straightforward in this code.
