If the filesystem has block size < page size and we end up calling
iomap_page_create() in iomap_page_mkwrite_actor(), the uptodate bits
would be zero, which causes us to skip writeback of blocks which are
!uptodate in iomap_writepage_map(). This can lead to user data loss.

Hello,
syzbot found the following issue on:
HEAD commit:23ee3e4e Merge tag 'pci-v5.8-fixes-2' of git://git.kernel...

Like commit 70f8a3ca68d3 ("mm: make mm->pinned_vm an atomic64 counter").
By making mm->locked_vm an atomic64 counter, we can safely modify it
without holding mmap_lock.
The reason for using atomic64 instead of atomic_long is to keep the same
as mm->pinned_vm, and there is no need to worry about

Jin Yao reported issue with possible conflict between raw
events and term values in pmu event syntax.
Currently following syntax is resolved as raw event with
0xead value:
uncore_imc_free_running/read/
instead of using 'read' term from uncore_imc_free_running pmu,
because 'read' is correct raw
Adding support to specify raw event with 'r0' syntax within
pmu term syntax like:
-e cpu/r0xdead/
It will be used to specify raw events in cases where they conflict
with real pmu terms, like 'read', which is valid raw event syntax,
but also a possible pmu term name as reported by Jin Yao.

Factor out a path_mount helper that takes a struct path * instead of the
actual file name. This will allow to convert the init and devtmpfs code
to properly mount based on a kernel pointer instead of relying on the
implicit set_fs(KERNEL_DS) during early init.

Set ramdisk_execute_command to "/init" at compile time. The command
line can still override it, but this saves a few instructions and
removes a NULL check.

Add a simple helper to check if a file exists based on kernel space file
name and switch the early init code over to it. Note that this
theoretically changes behavior as it always is based on the effective
permissions. But during early init that doesn't make a difference.

Hi Al and Linus,
currently a lot of the file system calls in the early in code (and the
devtmpfs kthread) rely on the implicit set_fs(KERNEL_DS) during boot.
This is one of the few last remaining places we need to deal with to kill
off set_fs entirely, so this series adds new helpers that take
