DEBUG_INFO options is selected, so there is no need to have it

not contain it.)
So remove it from the files, which fixes the build issues due to this

Syzbot recently found a number of issues related to incremental-fs
(see bug numbers below). All have to do with the fact that incr-fs
allows mounts of the same source and target multiple times.
This is a design decision and the user space component "Data Loader"
expects this to work for app re-install use case.
The mounting depth needs to be controlled, however, and only allowed
to be two levels deep. In case of more than two mount attempts the
driver needs to return an error.
In case of the issues listed below the common pattern is that the
reproducer calls:
mount("./file0", "./file0", "incremental-fs", 0, NULL)
many times and then invokes a file operation like chmod, setxattr,
or open on the ./file0. This causes a recursive call for all the
mounted instances, which eventually causes a stack overflow and
a kernel crash:
BUG: stack guard page was hit at ffffc90000c0fff8
kernel stack overflow (double-fault): 0000 [#1] PREEMPT SMP KASAN
This change also cleans up the mount error path to properly clean
allocated resources and call deactivate_locked_super(), which
causes the incfs_kill_sb() to be called, where the sb is freed.

In order to support CONFIG_UAPI_HEADER_TEST=y with a bionic sysroot
using prebuilt bionic from the NDK, we need to set a different target
triple for USERCFLAGS than what's used when cross compiling the kernel

In include/uapi/linux/tipc_config.h, there's a comment that it includes
arpa/inet.h for ntohs; but ntohs is not defined in any UAPI header. For
now, reuse the definitions from include/linux/byteorder/generic.h, since
the various conversion functions do exist in UAPI headers:
include/uapi/linux/byteorder/big_endian.h
include/uapi/linux/byteorder/little_endian.h
We would like to get to the point where we can build UAPI header tests
with -nostdinc, meaning that kernel UAPI headers should not have a
circular dependency on libc headers.

When you compile-test UAPI headers (CONFIG_UAPI_HEADER_TEST=y) with
Clang, they are currently compiled for the host target (likely x86_64)
regardless of the given ARCH=.
In fact, some exported headers include libc headers. For example,
include/uapi/linux/agpgart.h includes <stdlib.h> after being exported.
The header search paths should match to the target we are compiling
them for.
Pick up the --target triple from KBUILD_CFLAGS in the same ways as
commit 7f58b487e9 ("kbuild: make Clang build userprogs for target
architecture").

Allow additional arguments be passed to userprogs compilation.
Reproducible clang builds need to provide a sysroot and gcc path to
ensure the same toolchain is used across hosts. KCFLAGS is not currently
used for any user programs compilation, so add new USERCFLAGS and
USERLDFLAGS which serves similar purpose as HOSTCFLAGS/HOSTLDFLAGS.
Clang might detect GCC installation on hosts which have it installed
to a default location in /. With addition of these environment
variables, you can specify flags such as:
$ make USERCFLAGS=--sysroot=/path/to/sysroot
This can also be used to specify different sysroots such as musl or
bionic which may be installed on the host in paths that the compiler
may not search by default.

Clang warns:

default:

break;
1 error generated.
Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

The synchronous wakeup interface is available only for the
interruptible wakeup. Add it for normal wakeup and use this
synchronous wakeup interface to wakeup the userspace daemon.
Scheduler can make use of this hint to find a better CPU for
the waker task.
With this change the performance numbers for compress, decompress
and copy use-cases on /sdcard path has improved by ~30%.
Use-case details:
1. copy 10000 files of each 4k size into /sdcard path
2. use any File explorer application that has compress/decompress
support
3. start compress/decompress and capture the time.
