We can replace l_wait_event() with wait_event_noload_timeout() here providing we call the timeout function when wait_event_timeout() returns zero. Signed-off-by: NeilBrown --- drivers/staging/lustre/lustre/ptlrpc/client.c | 12

[PATCH 08/16] staging: lustre: open code polling loop instead of using l_wait_event()

Two places that LWI_TIMEOUT_INTERVAL() is used, the outcome is a simple polling loop that polls every second for some event (with a limit). So write a simple loop to make this more apparent. Signed-off-by: NeilBrown --- drivers/staging/lustre/lustre/llite/llite_lib.c | 11 +--

[PATCH 05/16] staging: lustre: introduce and use l_wait_event_abortable()

lustre sometimes wants to wait for an event, but abort if one of a specific list of signals arrives. This is a little bit like wait_event_killable(), except that the signals are identified a different way. So introduce l_wait_event_abortable() which provides this functionality. Having separate

[PATCH 02/16] staging: lustre: replace simple cases of l_wait_event() with wait_event().

When the lwi arg is full of zeros, l_wait_event() behaves almost identically to the standard wait_event() interface, so use that instead. The only difference in behavior is that l_wait_event() blocks all signals and uses an TASK_INTERRUPTIBLE wait, while wait_event() does not block signals, but

[PATCH 03/16] staging: lustre: discard cfs_time_seconds()

cfs_time_seconds() converts a number of second to the matching number of jiffies. The standard way to do this in Linux is "* HZ". So discard cfs_time_seconds() and use "* HZ" instead. Signed-off-by: NeilBrown --- .../lustre/include/linux/libcfs/libcfs_debug.h |4 ++--

[PATCH 04/16] staging: lustre: use wait_event_timeout() where appropriate.

When the lwi arg has a timeout, but no timeout callback function, l_wait_event() acts much the same as wait_event_timeout() - the wait is not interruptible and simply waits for the event or the timeouts. The most noticable difference is that the return value is -ETIMEDOUT or 0, rather than 0 or
