* | tty: disassociate_ctty() sends the extra SIGCONTOleg Nesterov2013-09-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Starting from v3.10 (probably commit f91e2590410b: "tty: Signal foreground group processes in hangup") disassociate_ctty() sends SIGCONT if tty && on_exit. This breaks LSB test-suite, in particular test8 in _exit.c and test40 in sigcon5.c. Put the "!on_exit" check back to restore the old behaviour. Review by Peter Hurley: "Yes, this regression was introduced by me in that commit. The effect of the regression is that ptys will receive a SIGCONT when, in similar circumstances, ttys would not. The fact that two test vectors accidentally tripped over this regression suggests that some other apps may as well.

The previous "marvell,armada-370-xp-timer" compatible is removed and two new compatible strings are introduced: "marvell,armada-xp-timer" and "marvell,armada-370-timer". The rationale behind this change is that the Armada 370 SoC and the Armada XP SoC timers are not really compatible: * Armada 370 has no 25 MHz fixed timer. * Armada XP cannot work properly without such 25 MHz fixed timer as doing otherwise leads to using a clocksource whose frequency varies when doing cpufreq frequency changes. This commit also removes the "marvell,timer-25Mhz" property, given it's now meaningless.

Unfortunately, the broadcast device could wake up any CPU, including an idle one which is not concerned by the wake up at all. This implies, in the worst case, an idle CPU will wake up to send an IPI to another idle cpu. This patch fixes this for ARM platforms using timer-sp, by setting CLOCK_EVT_FEAT_DYNIRQ feature.

| * | | | cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscacheSachin Prabhu2013-09-131-3/+7

This completion function unlocks the page once it has been populated from cache. The module then attempts to unlock the page a second time in cifs_readpage() which leads to warning messages. In case of a successful call to fscache_read_or_alloc_page() we should skip the second unlock_page() since this will be called by the cifs_readpage_from_fscache_complete() once the page has been populated by fscache. With the modifications to cifs_readpage_worker(), we will need to re-grab the page lock in cifs_write_begin(). The problem was first noticed when testing new fscache patches for cifs. https://bugzilla.redhat.com/show_bug.cgi?id=1005737 Signed-off-by: Sachin Prabhu <sprabhu@redhat.com> Reviewed-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <smfrench@gmail.com>

If the WL subsystem detects that no wear leveling is needed it cancels the operation and drops the gained PEB. In this case we have to put the PEB back into the free list.
