fnic: fnic Control Path Trace Utility
Fnic Ctlr Path Trace utility is a tracing functionality built directly into fnic
driver to trace the control path frames like discovery, FLOGI request/reply,
PLOGI request/reply, link event etc. It will be one trace file for all fnics.
It will help us to debug and resolve the discovery and initialization related
issues in more convenient way. This trace information includes time stamp,
Host Number, Frame type, Frame Length and Frame. By default,64 pages are
allocated but we can change the number of allocated pages by module parameter
fnic_fc_trace_max_page. Each entry is of 256 byte and available entries are
depends on allocated number of pages. We can turn on or off the fnic control

fnic: NoFIP solicitation frame in NONFIP mode and changed IO Throttle count
This patch contains following three minor fixes.
1) During Probe, fnic was sending FIP solicitation in Non FIP mode which is not
expected, setting the internal fip state to Non FIP mode explicitly, avoids
sending FIP frame.
2) When target goes offline, all outstanding IOs belong to the target will be
terminated by driver, If the termination count is high, then it influences
firmware responsiveness. To improve the responsiveness, default IO throttle
count is reduced to 256.
3) Accessing Virtual Fabric Id (vfid) and fc_map of Fibre-Channel Forwarder(FCF)
is invalid in fnic driver when Clear Virtual Link(CVL) is received prior to
receiving flogi reject from switch. As CVL clears all FCFs.

x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall()
With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:
(u64)(tk->wall_to_monotonic.tv_nsec << tk->shift)
instead of
((u64)tk->wall_to_monotonic.tv_nsec << tk->shift)
So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up
with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in
the subsequent 'while' loop.

The replacement of the 'count' variable by two variables 'incs' and

in parallel with some cleanup in the trace subsystem, and was integrated

Unfortunately, the formula for this replacement was wrong in the tracing

commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in

concurrency, so we can't use tasklet here, the patch need to be

fanotify: fix -EOVERFLOW with large files on 64-bit
On 64-bit systems, O_LARGEFILE is automatically added to flags inside
the open() syscall (also openat(), blkdev_open(), etc). Userspace
therefore defines O_LARGEFILE to be 0 - you can use it, but it's a
no-op. Everything should be O_LARGEFILE by default.
But: when fanotify does create_fd() it uses dentry_open(), which skips
all that. And userspace can't set O_LARGEFILE in fanotify_init()
because it's defined to 0. So if fanotify gets an event regarding a
large file, the read() will just fail with -EOVERFLOW.
This patch adds O_LARGEFILE to fanotify_init()'s event_f_flags on 64-bit
systems, using the same test as open()/openat()/etc.

revert "mm: vmscan: do not swap anon pages just because free+file is low"
This reverts commit
0bf1457f0cfc ("mm: vmscan: do not swap anon pages
just because free+file is low") because it introduced a regression in
mostly-anonymous workloads, where reclaim would become ineffective and
trap every allocating task in direct reclaim.
The problem is that there is a runaway feedback loop in the scan balance
between file and anon, where the balance tips heavily towards a tiny
thrashing file LRU and anonymous pages are no longer being looked at.
The commit in question removed the safe guard that would detect such
situations and respond with forced anonymous reclaim.
This commit was part of a series to fix premature swapping in loads with
relatively little cache, and while it made a small difference, the cure
is obviously worse than the disease. Revert it.

autofs: fix lockref lookup
autofs needs to be able to see private data dentry flags for its dentrys
that are being created but not yet hashed and for its dentrys that have
been rmdir()ed but not yet freed. It needs to do this so it can block
processes in these states until a status has been returned to indicate
the given operation is complete.
It does this by keeping two lists, active and expring, of dentrys in
this state and uses ->d_release() to keep them stable while it checks
the reference count to determine if they should be used.
But with the recent lockref changes dentrys being freed sometimes don't
transition to a reference count of 0 before being freed so autofs can
occassionally use a dentry that is invalid which can lead to a panic.

After commit
0cd6144aadd2 ("mm + fs: prepare for non-page entries in
page cache radix trees") this comment and BUG() are out of date because
exceptional entries can now appear in all mappings - as shadows of
recently evicted pages.
However, as Hugh Dickins notes,
"it is truly surprising for a PAGECACHE_TAG_WRITEBACK (and probably
any other PAGECACHE_TAG_*) to appear on an exceptional entry.
I expect it comes down to an occasional race in RCU lookup of the
radix_tree: lacking absolute synchronization, we might sometimes
catch an exceptional entry, with the tag which really belongs with
the unexceptional entry which was there an instant before."
And indeed, not only is the tree walk lockless, the tags are also read
in chunks, one radix tree node at a time. There is plenty of time for
page reclaim to swoop in and replace a page that was already looked up
as tagged with a shadow entry.
Remove the BUG() and update the comment. While reviewing all other
lookup sites for whether they properly deal with shadow entries of
evicted pages, update all the comments and fix memcg file charge moving
to not miss shmem/tmpfs swapcache pages.

mm/compaction: make isolate_freepages start at pageblock boundary
The compaction freepage scanner implementation in isolate_freepages()
starts by taking the current cc->free_pfn value as the first pfn. In a
for loop, it scans from this first pfn to the end of the pageblock, and
then subtracts pageblock_nr_pages from the first pfn to obtain the first
pfn for the next for loop iteration.
This means that when cc->free_pfn starts at offset X rather than being
aligned on pageblock boundary, the scanner will start at offset X in all
scanned pageblock, ignoring potentially many free pages. Currently this
can happen when
a) zone's end pfn is not pageblock aligned, or
b) through zone->compact_cached_free_pfn with CONFIG_HOLES_IN_ZONE
enabled and a hole spanning the beginning of a pageblock
This patch fixes the problem by aligning the initial pfn in
isolate_freepages() to pageblock boundary. This also permits replacing
the end-of-pageblock alignment within the for loop with a simple
pageblock_nr_pages increment.

HPAGE_SHIFT == 0 in this configuration, which indicates that hugepages

This does make hugetlbfs not supported (not registered at all) in this
