X-Git-Tag: v2.6.24-rc7~13^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e6e21970baff4845de74584e2efc8c964a55d574;p=pandora-kernel.git NFSv4: Fix open_to_lock_owner sequenceid allocation... NFSv4 file locking is currently completely broken since it doesn't respect the OPEN sequencing when it is given an unconfirmed lock_owner and needs to do an open_to_lock_owner. Worse: it breaks the sunrpc rules by doing a GFP_KERNEL allocation inside an rpciod callback. Fix is to preallocate the open seqid structure in nfs4_alloc_lockdata if we see that the lock_owner is unconfirmed. Then, in nfs4_lock_prepare() we wait for either the open_seqid, if the lock_owner is still unconfirmed, or else fall back to waiting on the standard lock_seqid.
