[RFC PATCH v2 0/2] mm: remove extra ZONE_DEVICE struct page refcount
Matthew Wilcox, Ira Weiny, and others have complained that ZONE_DEVICE
struct page reference counting is ugly because they are "free" when the
reference count is one instead of zero. This leads to explicit checks
for ZONE_DEVICE pages in places like put_page(), GUP, THP splitting, and
page migration which have to adjust the expected reference count when
determining if the page is

Win95 and Smbmount
Hi,
When I "smbmount" a shareable drive on my linux box, the result of the "ls"
command
is often false.
(Kernel is compiled with "SMB Win95 bug work around" and "SMB filesystems
support",
Linux 2.0.34, RedHat 5.1, Samba 1.9.18p5)
What can I do to solve my problem ???
Thanks a lot for your help.

Right, the iSCSI target driver uses signals to wake up threads (see also the
send_sig() calls in the iSCSI target code).

virtio balloon: do not call blocking ops when !TASK_RUNNING

wait_event_interruptible(vb->config_change,
(diff = towards_target(vb)) != 0
|| vb->need_stats_update
|| kthread_should_stop()
|| freezing(current));
wait_event_interruptible() sets the state of the current task to
TASK_INTERRUPTIBLE, then checks the condition. The condition contains
towards_target() which reads the virtio config space via virtio_cread().
On s390, this then triggers virtio_ccw_get_config() - and this function
calls some other functions again that might sleep (e.g. kzalloc or
wait_event in ccw_io_helper) ......
