Add a new UFFD_USER_MODE_ONLY flag for userfaultfd(2) that makes
the resulting userfaultfd object refuse to handle faults from kernel

the kernel code to fail with EFA

With this change, when the knob is set to 0, it allows unprivileged

In this mode, an unprivileged user (without SYS_CAP_PTRACE capability)
must pass UFFD_USER_MODE_ONLY

The BDI_CAP_STABLE_WRITES is one of the few bits of information in the
backing_dev_info shared between the block drivers and the writeback code.
To help untangling the dependency replace it with a queue flag and a
superblock flag derived from it. This also helps with the case of e.g.

Hi Jens,
this series contains a bunch of different BDI cleanups. The biggest item
is to isolate block drivers from the BDI in preparation of changing the
lifetime of the block device BDI in a follow up series.

Replace BDI_CAP_NO_ACCT_WB with a positive BDI_CAP_WRITEBACK_ACCT to

Support the MIPS architecture using the ins_ops association
method. With this patch, perf-annotate can work well on MIPS.
Testing it with a perf.data file collected on a mips machine:
$./perf annotate -i perf.data

If DCACHE_REFERENCED is set, fast_dput() will return true, and then
retain_dentry() have no chance to check DCACHE_DONTCACHE. As a result,
the dentry won't be killed and the corresponding inode can't be evicted.
In the following example, the DAX policy can't take effects unless we
do a drop_caches

Hi Qing,
It looks like all vivo guys patch has 'charset=y' problem and
mess code which fails on a success 'git am'. I have to repeat
the same reminder again and again...
Could you guys double your patches before send out? and make
sure docs looks good on webpage, like

V1: Introduces a retry loop that attempts a CMA allocation a finite
number of times before giving up:

raised a page pinning example which precludes d
CMA allocations will fail if 'pinned' pages are in a CMA area, since we
cannot migrate pinned pages. The _refcount of a struct page being greater
than _mapcount for that page can cause pinning for anonymous pages. This
is because try_to_unmap(), which (1) is called in the CMA allocation path,
