Subject: Currently nfs4mount() sets the retry value to 10000 on both fg and bg
X-Git-Tag: nfs-utils-1-1-3~52
X-Git-Url: https://git.decadent.org.uk/gitweb/?p=nfs-utils.git;a=commitdiff_plain;h=5f7cc524008a7dc548a71f4c7b0d39759371a37a;ds=sidebyside

Currently nfs4mount() sets the retry value to 10000 on both fg and bg
mounts. It should be 2 for fg and 10000 for bg. nfsmount() sets it
properly, but there is a potential corner case. If someone explicitly
sets retry=10000 on a fg mount, then it will be reset to 2.

Fix this by having retry default to -1 for both flavors, and then reset if
needed after the mount options have been parsed.
