A misplaced #endif causes link errors related to pcim_*() functions.
This is because pcim_*() functions are related to CONFIG_PCI option,
however these are not related to CONFIG_HAS_IOPORT option. Therefore,
when CONFIG_PCI is enabled and CONFIG_HAS_IOPORT is not enabled, it makes
link errors related to pcim_*() functions as below:
drivers/ata/libata-sff.c:3233: undefined reference to `pcim_iomap_regions'

This patch addresses a v3.5+ regression in iscsi-target where TX thread
process context -> handle_response_queue() execution is allowed to run
unbounded while servicing constant outgoing flow of ISTATE_SEND_DATAIN
response state.
This ends up preventing memory release of StatSN acknowledged commands
in a timely manner when under heavy large block streaming DATAIN
workloads.
The regression bug was initially introduced with:
commit 6f3c0e69a9c20441bdc6d3b2d18b83b244384ec6
Author: Andy Grover <agrover@redhat.com>
Date: Tue Apr 3 15:51:09 2012 -0700
target/iscsi: Refactor target_tx_thread immediate+response queue loops
Go ahead and follow original iscsi_target_tx_thread() logic and check
to break for immediate queue processing after each DataIN Sequence and/or
Response PDU has been sent.

When walking down the path on the server, it's possible to hit a
symlink. The path walking code assumes that the caller will handle that
situation properly, but cifs_get_root() isn't set up for it. This patch
prevents the oops by simply returning an error.
A better solution would be to try and chase the symlinks here, but that's
fairly complicated to handle.

On non-BIOS platforms it is possible that the BIOS data area contains
garbage instead of being zeroed or something equivalent (firmware
people: we are talking of 1.5K here, so please do the sane thing.)
We need on the order of 20-30K of low memory in order to boot, which
may grow up to < 64K in the future. We probably want to avoid the
lowest of the low memory. At the same time, it seems extremely
unlikely that a legitimate EBDA would ever reach down to the 128K
(which would require it to be over half a megabyte in size.) Thus,
pick 128K as the cutoff for "this is insane, ignore." We may still
end up reserving a bunch of extra memory on the low megabyte, but that
is not really a major issue these days. In the worst case we lose
512K of RAM.
This code really should be merged with trim_bios_range() in
arch/x86/kernel/setup.c, but that is a bigger patch for a later merge
window.

ext4: fix extent status tree regression for file systems > 512GB
|
|
This fixes a regression introduced by commit f7fec032aa782. The
problem was that the extents status flags caused us to mask out block
numbers smaller than 2**28 blocks. Since we didn't test with file
systems smaller than 512GB, we didn't notice this during the
development cycle.
A typical failure looks like this:
EXT4-fs error (device sdb1): htree_dirblock_to_tree:919: inode #172235804: block
152052301: comm ls: bad entry in directory: rec_len is smaller than minimal -
offset=0(0), inode=0, rec_len=0, name_len=0
... where 'debugfs -R "stat <172235804>" /dev/sdb1' reports that the
inode has block number 688923213. When viewed in hex, block number
152052301 (from the syslog) is 0x910224D, while block number 688923213
is 0x2910224D. Note the missing "0x20000000" in the block number.

compares as NULL
When taking an address of an extern array, gcc quite naturally should be
able to say "an address of an object can never be NULL" and just
optimize away the test entirely.
However, the new alternate sysrq reset code (commit 154b7a489a5b:
"Input: sysrq - allow specifying alternate reset sequence") did exactly
that, and declared platform_sysrq_reset_seq[] as a weak array, and
expecting that testing the address of the array would show whether it
actually got linked against something or not.
And that doesn't work with all gcc versions. Clearly it works with
*some* versions of gcc, and maybe it's even supposed to work, but it
really is a very fragile concept.
So instead of testing the address of the weak variable, just create a
weak instance of that array that is empty. If some platform then has a
real platform_sysrq_reset_seq[] that overrides our weak one, the linker
will switch to that one, and it all works without any run-time
conditionals at all.

The stack vma is designed to grow automatically (marked with VM_GROWSUP
or VM_GROWSDOWN depending on architecture) when an access is made beyond
the existing boundary. However, particularly if you have not limited
your stack at all ("ulimit -s unlimited"), this can cause the stack to
grow even if the access was really just one past *another* segment.
And that's wrong, especially since we first grow the segment, but then
immediately later enforce the stack guard page on the last page of the
segment. So _despite_ first growing the stack segment as a result of
the access, the kernel will then make the access cause a SIGSEGV anyway!
So do the same logic as the guard page check does, and consider an
access to within one page of the next segment to be a bad access, rather
than growing the stack to abut the next segment.

ptrace regset interface relies on ELF_NGREG for ceiling the size of user
request. So any larger request (even if legit) would be clipped.
The existing def of ELF_NGREG didn't use user_regs_struct and was
technically one placeholder short (stop_pc) - although the current code
would still work because pt_regs includes a bunch of extra fields,
making
ELF_NGREG >= sizeof(struct user_regs_struct)/sizeof(long)
But we need to remove this ambiguity, specially since pt_regs should NOT
be directly associated with with anything userspace-ish.

All drivers which implement this need to have some sort of refcount to
allow concurrent vmap usage. Hence implement this in the dma-buf core.
To protect against concurrent calls we need a lock, which potentially
causes new funny locking inversions. But this shouldn't be a problem
for exporters with statically allocated backing storage, and more
dynamic drivers have decent issues already anyway.
Inspired by some refactoring patches from Aaron Plattner, who
implemented the same idea, but only for drm/prime drivers.
v2: Check in dma_buf_release that no dangling vmaps are left.
Suggested by Aaron Plattner. We might want to do similar checks for
attachments, but that's for another patch. Also fix up ERR_PTR return
for vmap.
v3: Check whether the passed-in vmap address matches with the cached
one for vunmap. Eventually we might want to remove that parameter -
compared to the kmap functions there's no need for the vaddr for
unmapping. Suggested by Chris Wilson.
v4: Fix a brown-paper-bag bug spotted by Aaron Plattner.

The legacy behavior adds the pgid seed and pool together as the input for
CRUSH. That is problematic because each pool's PGs end up mapping to the
same OSDs: 1.5 == 2.4 == 3.3 == ...
Instead, if the HASHPSPOOL flag is set, we has the ps and pool together and
feed that into CRUSH. This ensures that two adjacent pools will map to
an independent pseudorandom set of OSDs.
Advertise our support for this via a protocol feature flag.

Use the new version of the encoding for osd requests and replies. In the
process, update the way we are tracking request ops and reply lengths and
results in the struct ceph_osd_request. Update the rbd and fs/ceph users
appropriately.
The main changes are:
- we keep pointers into the request memory for fields we need to update
each time the request is sent out over the wire
- we keep information about the result in an array in the request struct
where the users can easily get at it.

Instead of using the old ceph_object_layout struct, update our internal
ceph_calc_object_layout method to use the ceph_pg type. This allows us to
pass the full 32-bit precision of the pgid.seed to the callers. It also
allows some callers to avoid reaching into the request structures for the
struct ceph_object_layout fields.

The only thing type-specific osd completion functions do with their
osd op parameter is (in some cases) extract the number of bytes
transferred from it. In the other cases, the xferred bytes field
is not used, and total message data transfer byte count (which may
well be zero) is used.
Just set the object request transfer count in the main osd request
callback function and provide that to the other routines. There is
then no longer any need to pass the op pointer to the type-specific
completion routines, so drop those parameters.
Stop doing anything with the total message data length.

Pull ext4 updates from Theodore Ts'o:
"The one new feature added in this patch series is the ability to use
the "punch hole" functionality for inodes that are not using extent
maps.
In the bug fix category, we fixed some races in the AIO and fstrim
code, and some potential NULL pointer dereferences and memory leaks in
error handling code paths.
In the optimization category, we fixed a performance regression in the
jbd2 layer introduced by commit d9b01934d56a ("jbd: fix fsync() tid
wraparound bug", introduced in v3.0) which shows up in the AIM7
benchmark. We also further optimized jbd2 by minimize the amount of
time that transaction handles are held active.
This patch series also features some additional enhancement of the
extent status tree, which is now used to cache extent information in a
more efficient/compact form than what we use on-disk."
