Change subject: Decouple upvector wait and nfs_init wait
......................................................................
Decouple upvector wait and nfs_init wait
Currently up_ready_wait() calls nfs_init_wait(). GPFS upcall thread
calls up_ready_wait() while holding gpfs_fs->upvector_mutex. This very
same mutex is needed by the thread that creates exports which is
responsible for setting nfs_init.init_complete condition! This leads
gpfs_fs->upvector_mutex and nfs_init.init_complete ABBA deadlock between
GPFS upcall thread and the main thread reading/creating exports.
Fix is to avoid up_ready_wait() waiting the for the
nfs_init.init_complete condition. Let the GPFS upcall thread explicitly
wait for nfs_init.init_complete.
