I do not know how reliably this function works, but it seems dangerous
to me, at least.
The function call
strchr(sources, '\n');
... continues searching until it finds '\n' or it reaches the '\0'
terminator. In other words, 'sources' should be a null-terminated
string.
However, grab_file()
new_module() conditionally strips the .o because the modname has .o
suffix when it is called from read_symbols(), but no .o when it is
called from read_dump().
It is clearer to strip .o in read_symbols().
I also used flexible-array for mod->name.

The meaning of 'skip' is obscure since it does not explain
"what to skip".
mod->skip is set when it is vmlinux or the module info came from
a dump file.
So, mod->skip is equivalent to (mod->is_vmlinux || mod->from_dump).
For the check in write_namespace_deps_files(), mod->is_vmlinux is
unneeded
is_vmlinux() is called in several places to check whether the current
module is vmlinux or not.
It is faster and clearer to check mod->is_vmlinux flag.

$(firstword ...) in scripts/Makefile.modpost was added by commit

to build multiple external module directories.
This feature has been broken for a while. Remove the bitrotten code, and
stop parsing if M or KBUILD_EXTMOD
Now that is_vmlinux() is called only in new_module(), we can inline
the function call.
modname is the basename with '.o' is stripped. No need to compare it
with 'vmlinux.o'.
vmlinux is always located at the current working directory. No need

The meaning of sym->kernel is obscure; it is set for in-kernel symbols
loaded from Modules.symver. This happens only when we are building
external modules, and it is used to determine whether to dump symbols
to $(KBUILD_EXTMOD)/Modules.symver
It is clearer to remember whether the symbol or module
grab_file() mmaps a file, but it is not so efficient here because
get_next_line() copies every line to the temporary buffer anyway.
read_text_file() and get_line() are simpler. get_line() exploits the
library function strchr().

If modpost fails to load a symbol dump file, it cannot check unresolved
symbols, hence module dependency will not be added. Nor CRCs can be added.
Currently, external module builds check only $(objtree)/Module.symvers,
but it should check files specified by KBUILD_EXTRA_SYMBOLS as well.
Print
Previously, the -i option had two functions; load a symbol dump file,
and set the external_module flag.
I want to assign a dedicate option for each of them.
Going forward, the -i is used to load a symbol dump file, and the -e
to set the external_module flag.
With this, we will be able to use -i
check_exports() is never called for vmlinux because mod->skip is set
for vmlinux.
Hence, check_for_gpl_usage() and check_for_unused() are not called
for vmlinux, either. is_vmlinux() is always false here.
Remove the is_vmlinux() calls, and hard-code the ".ko" suffix.

Now that there is no difference in the functionality of -i and -e,

modpost: add read_text_file() and get_line() helpers
modpost: fix potential mmap'ed file overrun in get_src_version()
modpost: re-add warning about missing
The three calls of get_modinfo() ("license", "import_ns", "version")
always return NULL for vmlinux because the built-in module info is
prefixed with __MODULE_INFO_PREFIX.
It is harmless to call get_modinfo(), but there is no point to search
for what apparently does not exist.
Signed-off-by:
check_exports() does not print warnings about unresolved symbols if
vmlinux is missing because there would be too many.
This situation happens when you do 'make modules' from the clean
tree, or compile external modules against a kernel tree that has
not been completely built.
Not checking
One problem of grab_file() is that it cannot distinguish the following
two cases:
- I cannot read the file (the file does not exist, or read permission
is not set)
- It can read the file, but the file size is zero
This is because grab_file() calls mmap(), which requires the mapped
length
As far as I understood, this code gets rid of '$Revision$' or '$Revision:'
of CVS, RCS or whatever in MODULE_VERSION() tags.
Remove the primeval code.

The full build runs modpost twice, first for vmlinux.o and second for
modules.
The first pass dumps all the vmlinux symbols into Module.symvers, but
the second pass parses vmlinux again instead of reusing the dump file,
presumably because it needs to avoid accumulating stale symbols.
Loading
This reverts 4be40e22233c ("kbuild: do not emit src version warning for
non-modules").
I do not fully understand what that commit addressed, but commit
91341d4b2c19 ("kbuild: introduce new option to enhance section mismatch
analysis") introduced partial section checks by using modpost. built-in.o
Previously, there were two cases where mod->is_dot_o is unset:
[1] the executable 'vmlinux' in the second pass of modpost
[2] modules loaded by read_dump()
I think [1] was intended usage to distinguish 'vmlinux.o' and 'vmlinux'.
Now that modpost does not parse the executable 'vmlinux', this case
Currently, modpost reads extra symbol dump files in the reverse order.
If '-e foo -e bar' is given, modpost reads bar, foo, in this order.
This is probably not a big deal, but there is no good reason to reverse
the order. Read files in the given order.

If req->io is not NULL, it's already prepared. Don't do it again,
it's dangerous.

[2] fixes FORCE_ASYNC. I don't want to go through every bit, so
not sure whether this is an actual issue with [1], but it's just
safer this way. Please, consider it for-5.7
IMHO, all preparation thing became a bit messy, definitely could use
some rethinking in the future.
Pavel Begunkov (2):
As for other not inlined requests, alloc req->io for FORCE_ASYNC reqs,
so they can be prepared properly.

Independent cleanups, that's it.

req->flags stores all sqe->flags. After checking that sqe->flags are
valid set if IOSQE* flags, no need to double check it, just forward them
all.

A submission is "async" IIF it's done by SQPOLL thread. Instead of
passing @async flag into io_submit_sqes(), deduce it from ctx->flags.

io_file_put() deals with flushing state's file refs, adding "state" to
its name makes it a bit clearer. Also, avoid double check of
state->file in __io_file_get() in some cases.

Add IORING_OP_TEE implementing tee(2) support. Almost identical to
splice bits, but without offsets.

Split and test functionality separately, better cover registered files
cases, and validate file\pipe actual data.
