In obdclass/lprocfs_status.c
But in lustre/include/lprocfs_status.h, the __user annotation is missing for
the attribute buffer.
The correct prototype is the first one (the definition) since:
- This function is eventually called by the write() function pointer of an
instance of struct file_operations
- In this function, buffer is a parameter of copy_from_user()
- Before the commit 73bb1da692d0dc3e93b9c9e29084d6a5dcbc37a6, the declaration
and the definition had the same prototype, but only the .c has been updated.

`struct pci230_private` has two members to manage the enabled interrupt
sources. `int_en` is the interrupt sources we want to be enabled and
`ier` is a shadow of the write-only interrupt enable register. They
have the same value most of the time. They differ in the interrupt
handler (`pci230_interrupt()`) itself when it temporarily clears bits in
the interrupt enable register and the `ier` member in order to unlatch
them in hardware, but leaves the `int_en` member alone. They also
differ in `pci230_ai_stop()` and `pci230_ao_stop()` which clear bits in
the `int_en` member and wait for the interrupt handler to finish before
copying the value to the `ier` member and the interrupt enable register.
Simplify the handling a bit, by making the `ier` member take on the role
of the `int_en` member, and allowing the value to differ from the
interrupt enable register while the interrupt handler is running.

Some counter channels may be required for AI commands and AO commands.
Depending on how the commands are set up, it may not be possible to run
both at the same time, so we keep some state and code to find out if the
required resources are busy or not.
The existing code is a bit unwieldy - the code for claiming resources
involves two `for` loops for example. Rewrite it to make it simpler.
The new code just has a bit-mask value for each shared resource (counter
channels), and an array indexed by resource "owners" (AI and AO
commands), so the code for claiming resources now just has a single loop
that checks that none of the other owners have claimed the wanted
resources.
Rename the functions involved, because the old names involving 'put' and
'get' suggested some sort of usage counting.

converts it to a comedi sample value. The AI sample may have 12 or 16
bits of resolution, depending on the board type, but 12-bit sample
values are in bits 15 to 4 of the register. The hardware value is
signed, 2's complement if set to a bipolar mode, or unsigned, straight
binary if set to a unipolar mode. To convert to a Comedi sample value
it may need shifting right by 4 bits, and the top bit of the sample
value may need to be toggled.
