Hello Malahal, I'd like you to do a code review. Please visit https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/495993 to review the following change. Change subject: [GPFS] Fix to let GPFS upcall thread exit at ganesha startup ...................................................................... [GPFS] Fix to let GPFS upcall thread exit at ganesha startup Currently during startup if GPFSFSAL_UP_Thread() gets called, it waits in nfs_init_wait() for init to complete. But if during startup gpfs_unclaim_filesystem() gets called, then the main thread may hang at pthread_join() for GPFS upcall thread, if the thread is waiting in nfs_init_wait(). To avoid this made use of 'stop_thread' variable in 'struct gpfs_filesystem', which is set to 'true' prior to calling pthread_join() in gpfs_unclaim_filesystem(). Also made changes to allow to pass timeout value to nfs_init_wait() which is now called in GPFSFSAL_UP_Thread() in while(1) loop, and after nfs_init_wait() completes if gpfs_fs->stop_thread==true then we return.
