For some long forgotten reason, the nfs_client cl_flags field is
initialised in nfs_get_client() instead of being initialised at
allocation time. This quirk was harmless until we moved the call to
nfs_create_rpc_client().
Fixes: dd99e9f98fbf ("NFSv4: Initialise connection to the server in nfs4_alloc_client()")

Once F2FS_IPU_FORCE policy is enabled in some cases:
a) f2fs forces to use F2FS_IPU_FORCE in a small-sized volume
b) user sets F2FS_IPU_FORCE policy via sysfs
Then we may fail to defragment file due to IPU policy check, it doesn't
make sense, let's introduce a new IPU policy to allow OPU during file
defragmentation.
In small-sized volume, let's enable F2FS_IPU_HONOR_OPU_WRITE policy
by default.

On an overcommitted system which is running multiple workloads of
varying priorities, it is preferred to trigger an oom-killer to kill a
low priority workload than to let the high priority workload receiving
ENOMEMs. On our memory overcommitted systems, we are seeing a lot of
ENOMEMs instead of oom-kills because io_uring_setup callchain is using
__GFP_NORETRY gfp flag which avoids the oom-killer. Let's remove it and
allow the oom-killer to kill a lower priority job.

In io_recv(), if import_single_range() fails, the @flags variable is
uninitialized, then it will goto out_free.
After the goto, the compiler doesn't know that (ret < min_ret) is
always true, so it thinks the "if ((flags & MSG_WAITALL) ..." path
could be taken.
The complaint comes from gcc-9 (Debian 9.3.0-22) 9.3.0:
```
fs/io_uring.c:5238 io_recvfrom() error: uninitialized symbol 'flags'
```
Fix this by bypassing the @ret and @flags check when
import_single_range() fails.
Reasons:
1. import_single_range() only returns -EFAULT when it fails.
2. At that point, @flags is uninitialized and shouldn't be read.

Pull xfs fixes from Darrick Wong:
"I was auditing operations in XFS that clear file privileges, and
realized that XFS' fallocate implementation drops suid/sgid but
doesn't clear file capabilities the same way that file writes and
reflink do.
There are VFS helpers that do it correctly, so refactor XFS to use
them. I also noticed that we weren't flushing the log at the correct
point in the fallocate operation, so that's fixed too.

modified instead of open-coding that incompletely.
- Fix fallocate to flush the log if the caller wanted synchronous
file updates"

Prior to ztailpacking feature, it's enough that each lcluster has
two pclusters at most, and the last pcluster should be turned into
an uncompressed pcluster when necessary. For example,
_________________________________________________
|_ pcluster n-2 _|_ pcluster n-1 _|____ EOFed ____|
which should be converted into:
_________________________________________________
|_ pcluster n-2 _|_ pcluster n-1 (uncompressed)' _|
That is fine since either pcluster n-1 or (uncompressed)' takes one
physical block.
However, after ztailpacking was supported, the game is changed since
the last pcluster can be inlined now. And such case above is quite
common for inlining small files. Therefore, in order to inline more
effectively, special EOF lclusters are now supported which can have
three parts at most, as illustrated below:
_________________________________________________
|_ pcluster n-2 _|_ pcluster n-1 _|____ EOFed ____|
^ i_size
Actually similar code exists in Yue Hu's original patchset [1], but I
removed this part on purpose. After evaluating more real cases with
small files, I've changed my mind.

This patch exposes max_discard_request, min_discard_issue_time,
mid_discard_issue_time, and max_discard_issue_time in sysfs. This will
allow the user to fine tune discard operations.

This patch unifies parameters related to how often discard is issued and
how many requests go out at the same time by placing them in
discard_cmd_control. The move will allow the parameters to be modified
in the future without relying on hard-coded values.

If we've reached the end of the directory, then cache that information
in the context so that we don't need to do an uncached readdir in order
to rediscover that fact.

If we're doing an uncached read of the directory, then we ideally want
to read only the exact set of entries that will fit in the buffer
supplied by the getdents() system call. So unlike the case where we're
reading into the page cache, let's send only one READDIR call, before
trying to fill up the buffer.

This code triggers a Smatch warning:
fs/ntfs3/fsntfs.c:1606 ntfs_bio_fill_1()
warn: variable dereferenced before check 'bio' (see line 1591)
The "bio" pointer cannot be NULL so there is no need to check.
Originally there was more extensive NULL checking but it was removed
because bio_alloc() will never fail if it is allowed to sleep.
Remove this check as well.

Also move the gfp_mask argument after the nr_vecs argument for a much
