Subject: nfs-utils: NFSv4: fix backgrounding
X-Git-Tag: nfs-utils-1-2-2-rc2~13
X-Git-Url: https://git.decadent.org.uk/gitweb/?a=commitdiff_plain;h=29e2293a69a75abf0ce1c85daff0b94c9875d56a;p=nfs-utils.git

nfs-utils: NFSv4: fix backgrounding

he nfsmount() function checks if !bg before running
switch(rpc_createerr.cf_stat). On the other hand, the nfs4mount()
function does not, and results in exiting the loop on the first
iteration even with the bg mount option.

NOTE: This and the previous patch ("nfs-utils: mount options can be lost
when using bg option") are relevant to non text-based mount options.

See https://bugzilla.redhat.com/show_bug.cgi?id=529370 for details.
