The caller allocated it, the caller should free it.
The only issue so far is that we could change the flp pointer even on an
error return if the fl_change callback failed. But we can simply move
the flp assignment after the fl_change invocation, as the callers don't
care about the flp return value if the setlease call failed.Signed-off-by: Christoph Hellwig

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1)As pointed out by Kerstin Jonsson , this
is due to CONFIG_32BIT not being defined, so the initramfs size field is
done as a 64-bit quad. On little-endian (like x86) this doesn matter,
but on a big-endian machine the 32-bit reads will see the (zero) high
bits.Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for
all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT,
which should be defined on all 64-bit arches.Signed-off-by: Geert Uytterhoeven
[ I think we should just make it "u64" on all architectures and get
rid of the whole #ifdef CONFIG_xxBIT - Linus ]

The NFSv4 server was initializing the dp->dl_flock pointer by the
somewhat ridiculous method of a locks_copy_lock callback.Now that setlease uses the passed-in lock instead of doing a copy,
dl_flock no longer gets set, resulting in the lock leaking on delegation
release, and later possible hangs (among other problems).So, initialize dl_flock and get rid of the callback.

Removing a lock shouldn't require any allocations; a failure due to
ENOMEM leaves the caller with a choice between retrying or giving up and

Even with the previous fix, we still are reading the iovecs once
to determine SGs needed, and then again later on. Preallocating
space for sg lists as part of rds_message seemed like a good idea
but it might be better to not do this. While working to redo that
code, this patch attempts to protect against userspace rewriting
the rds_iovec array between the first and second accesses.The consequences of this would be either a too-small or too-large
sg list array. Too large is not an issue. This patch changes all
callers of message_alloc_sgs to handle running out of preallocated
sgs, and fail gracefully.Signed-off-by: Andy Grover

Change rds_rdma_pages to take a passed-in rds_iovec array instead
of doing copy_from_user itself.Change rds_cmsg_rdma_args to copy rds_iovec array once only. This
eliminates the possibility of userspace changing it after our
sanity checks.Implement stack-based storage for small numbers of iovecs, based
on net/socket.c, to save an alloc in the extremely common case.Although this patch reduces iovec copies in cmsg_rdma_args to 1,
we still do another one in rds_rdma_extra_size. Getting rid of
that one will be trickier, so it'll be a separate patch.Signed-off-by: Andy Grover

rds_cmsg_rdma_args would still return success even if rds_rdma_pages
returned an error (or overflowed).Signed-off-by: Andy Grover
Signed-off-by: David S. Miller -
As reported by Thomas Pollet, the rdma page counting can overflow. We
get the rdma sizes in 64-bit unsigned entities, but then limit it to
UINT_MAX bytes and shift them down to pages (so with a possible "+1" for
an unaligned address).So each individual page count fits comfortably in an 'unsigned int' (not
even close to overflowing into signed), but as they are added up, they
might end up resulting in a signed return value. Which would be wrong.Catch the case of tot_pages turning negative, and return the appropriate
error code.Reported-by: Thomas Pollet

The btrfs merge looks like hell, because it changes fs-writeback.c, and
the crazy code has this repeated "estimate number of dirty pages"
counting that involves three different helper functions. And it's done
in two different places.Just unify that whole calculation as a "get_nr_dirty_pages()" helper
function, and the merge result will look half-way decent.Signed-off-by: Linus Torvalds
