Don't limit non-nested epoll paths
Commit 28d82dc1c4ed ("epoll: limit paths") that I did to limit the
number of possible wakeup paths in epoll is causing a few applications
to longer work (dovecot for one).
The original patch is really about limiting the amount of epoll nesting
(since epoll fds can be attached to other fds). Thus, we probably can
allow an unlimited number of paths of depth 1. My current patch limits
it at 1000. And enforce the limits on paths that have a greater depth.

This reverts commit d47a0ac7b6 (sch_sfq: dont put new flow at the end of

As Jesper found out, patch sounded great but has bad side effects.
In stress situation, pushing new flows in front of the queue can prevent
old flows doing any progress. Packets can stay in SFQ queue for
unlimited amount of time.
It's possible to add heuristics to limit this problem, but this would
add complexity outside of SFQ scope.
A more sensible answer to Dave Taht concerns (who reported the issued I
tried to solve in original commit) is probably to use a qdisc hierarchy
so that high prio packets dont enter a potentially crowded SFQ qdisc.

Pull media fixes from Mauro Carvalho Chehab:
"For 4 fixes for 3.3 (all trivial):
- uvc video driver: fixes a division by zero;
- davinci: add module.h to fix compilation;
- smsusb: fix the delivery system setting;
- smsdvb: the get_frontend implementation there is broken.
The smsdvb patch has 127 lines, but it is trivial: instead of
returning a cache of the set_frontend (with is wrong, as it doesn't
have the updated values for the data, and the implementation there is
buggy), it copies the information of the detected DVB parameters from
the smsdvb private structures into the corresponding DVBv5 struct
fields."

Pull target fixes from Nicholas Bellinger:
"This series addresses two recently reported regression bugs related to
legacy SCSI reservation usage in target core, and iscsi-target
reservation conflict handling.
The second patch in particular addresses possible data-corruption with
SCSI reservations that is specific to iscsi-target fabric LUNs with
multiple client writers. Both patches need to go into v3.2 stable
ASAP, and the branch based on the last target-pending/3.3-rc-fixes
HEAD.
Again, thanks to Martin Svec for his help to identify and address this
regression bug with iscsi-target."
strict_strtoul() writes a long but ->gamma_mode only has space to store an
int, so on 64 bit systems we end up scribbling over ->gamma_table_count as
well. I've changed it to use kstrtouint() instead.

prctl: use CAP_SYS_RESOURCE for PR_SET_MM option
CAP_SYS_ADMIN is already overloaded left and right, so to have more
fine-grained access control use CAP_SYS_RESOURCE here.
The CAP_SYS_RESOUCE is chosen because this prctl option allows a current
process to adjust some fields of memory map descriptor which rather
represents what the process owns: pointers to code, data, stack
segments, command line, auxiliary vector data and etc.

Incorrect definitions do not affect Tsi721 driver in its current default

memcg: free mem_cgroup by RCU to fix oops
After fixing the GPF in mem_cgroup_lru_del_list(), three times one
machine running a similar load (moving and removing memcgs while
swapping) has oopsed in mem_cgroup_zone_nr_lru_pages(), when retrieving
memcg zone numbers for get_scan_count() for shrink_mem_cgroup_zone():
this is where a struct mem_cgroup is first accessed after being chosen
by mem_cgroup_iter().
Just what protects a struct mem_cgroup from being freed, in between
mem_cgroup_iter()'s css_get_next() and its css_tryget()? css_tryget()
fails once css->refcnt is zero with CSS_REMOVED set in flags, yes: but
what if that memory is freed and reused for something else, which sets
"refcnt" non-zero? Hmm, and scope for an indefinite freeze if refcnt is
left at zero but flags are cleared.
It's tempting to move the css_tryget() into css_get_next(), to make it
really "get" the css, but I don't think that actually solves anything:
the same difficulty in moving from css_id found to stable css remains.
But we already have rcu_read_lock() around the two, so it's easily fixed
if __mem_cgroup_free() just uses kfree_rcu() to free mem_cgroup.
However, a big struct mem_cgroup is allocated with vzalloc() instead of
kzalloc(), and we're not allowed to vfree() at interrupt time: there
doesn't appear to be a general vfree_rcu() to help with this, so roll
our own using schedule_work(). The compiler decently removes
vfree_work() and vfree_rcu() when the config doesn't need them.

i2c-algo-bit: Fix spurious SCL timeouts under heavy load
When the system is under heavy load, there can be a significant delay
between the getscl() and time_after() calls inside sclhi(). That delay
may cause the time_after() check to trigger after SCL has gone high,
causing sclhi() to return -ETIMEDOUT.
To fix the problem, double check that SCL is still low after the
timeout has been reached, before deciding to return -ETIMEDOUT.
