Trace points never modify their arguments. Mark all the pag objects
passed to trace points. The exception is the xfs_ag_resv_class, which
uses the xfs_perag_resv helper that can't be marked const due to
other users modifying the returned structure.

In commit 11f4c3a53adde, we tried to simplify the extent lookup in
xfs_can_free_eofblocks so that it doesn't incur the overhead of all the
extra stuff that xfs_bmapi_read does around the iext lookup.
Unfortunately, this causes regressions on generic/603, xfs/108,
generic/219, xfs/173, generic/694, xfs/052, generic/230, and xfs/441
when always_cow is turned on. In all cases, the regressions take the
form of alwayscow files consuming rather more space than the golden
output is expecting. I observed that in all these cases, the cause of
the excess space usage was due to CoW fork delalloc reservations that go
beyond EOF.
For alwayscow files we allow posteof delalloc CoW reservations because
all writes go through the CoW fork. Recall that all extents in the CoW
fork are accounted for via i_delayed_blks, which means that prior to
this patch, we'd invoke xfs_free_eofblocks on first close if anything
was in the CoW fork. Now we don't do that.
Fix the problem by reverting the removal of the i_delayed_blks check.

Jinsu Lee reported a performance regression issue, after commit

inode, it will cause performace regression due to memory copy

It's fine to not force direct write to use buffered IO, as it

After enable 16K page size, an infinite loop may occur in
fiemap (fm_length=UINT64_MAX) on a file, such as the 16KB
scratch.img during the remount operation in Android.
The condition for whether fiemap continues to map is to check
whether the number of bytes corresponding to the next map.m_lblk
exceeds blks_to_bytes(inode,max_inode_blocks(inode)) if there are HOLE.
The latter does not take into account the maximum size of a file with 16KB
page size, so the loop cannot be jumped out.
The following is the fail trace:
When f2fs_map_blocks reaches map.m_lblk=3936, it needs to go to the
first direct node block, so the map is 3936 + 4090 = 8026,
The next map is the second direct node block, that is,
8026 + 4090 = 12116,
The next map is the first indirect node block, that is,
12116 + 4090 * 4090 = 16740216,
The next map is the second indirect node block, that is,
16740216 + 4090 * 4090 = 33468316,
The next map is the first double indirect node block, that is,
33468316 + 4090 * 4090 * 4090 = 68451397316
Since map.m_lblk represents the address of a block, which is 32
bits, truncation will occur, that is, 68451397316 becomes
4026887876, and the number of bytes corresponding to the block
number does not exceed blks_to_bytes(inode,max_inode_blocks(inode)),
so the loop will not be jumped out.
The next time, it will be considered that it should still be a
double indirect node block, that is,
4026887876 + 4090 * 4090 * 4090 = 72444816876, which will be
truncated to 3725340140, and the loop will not be jumped out.

To make it possible to put struct bin_attribute into read-only memory,
the sysfs core has to stop passing mutable pointers to the read() and
write() callbacks.
As there are numerous implementors of these callbacks throughout the
tree it's not possible to change all of them at once.
To enable a step-by-step transition, add new variants of the read() and
write() callbacks which differ only in the constness of the struct
bin_attribute argument.
As most binary attributes are defined through macros, extend these
macros to transparently handle both variants of callbacks to minimize
the churn during the transition.
As soon as all handlers are switch to the const variant, the non-const
one can be removed together with the transition machinery.

Several drivers need to dynamically calculate the size of an binary
attribute. Currently this is done by assigning attr->size from the
is_bin_visible() callback.
This has drawbacks:
* It is not documented.
* A single attribute can be instantiated multiple times, overwriting the
shared size field.
* It prevents the structure to be moved to read-only memory.
Introduce a new dedicated callback to calculate the size of the
attribute.

The DLM_LKF_QUECVT flag needs to be set for "upward" lock conversions to
ensure fairness, but setting it for "downward" lock conversions will
lead to a failure. The flag is currently set based on the GLF_BLOCKING
flag and it's not immediately obvious why this is correct. Simplify
things by figuring out if a lock conversion is "upward" by looking at
the before and after locking modes instead of relying on the
GLF_BLOCKING flag.

When function evict_should_delete() returns SHOULD_DEFER_EVICTION, gh is
never initialized, but that isn't obvious; if it did initialize gh and
then return SHOULD_DEFER_EVICTION, gfs2_evict_inode() would fail to
release it. To clarify the code, change gfs2_evict_inode() to always
check if gh needs to be released, no matter what evict_should_delete()
returns.

Randomize the delay of GLF_VERIFY_DELETE work. This avoids thundering
herd problems when multiple nodes schedule that kind of work in response
to an inode being unlinked remotely.

In the unlikely case that we're trying to queue GLF_TRY_TO_EVICT work
for an inode that already has GLF_VERIFY_DELETE work queued, we want to
make sure that the GLF_TRY_TO_EVICT work gets scheduled immediately
instead of waiting for the delayed work timer to expire.

Try to be a bit more clear and remove some duplications. We cannot
actually get rid of the verification step eventually, so remove the
comment saying so.

Function delete_work_func() was previously assuming that the
GLF_TRY_TO_EVICT and GLF_VERIFY_DELETE flags won't both be set at the
same time, but there probably are races in which that can happen, so
handle that case correctly.
