proc: introduce proc_create_single{,_data}

2018-05-16T05:23:35+00:00

Variants of proc_create{,_data} that directly take a seq_file show
callback and drastically reduces the boilerplate code in the callers.

All trivial callers converted over.

drivers/char: make efirtc.c driver explicitly non-modular

2015-09-21T02:32:35+00:00

The Kconfig for this driver is currently:

config EFI_RTC
        bool "EFI Real Time Clock Services"

...meaning that it currently is not being built as a module by anyone.
Lets remove all modular references, so that when reading the driver
there is no doubt it is builtin-only.

Since module_init translates to device_initcall in the non-modular
case, the init ordering remains unchanged with this commit.

We leave some tags like MODULE_LICENSE for documentation purposes.

efirtc: Don't use create_proc_read_entry()

2013-04-29T19:41:55+00:00

Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.

efirtc: explicitly set llseek to no_llseek

2009-12-16T15:19:59+00:00

Now that we've removed the BKL here, let's explicitly set llseek to
no_llseek since the default llseek is not used here.

The default_llseek function still contains the BKL.  When we are auditing
code to see if we can remove the BKL, this is one of the hidden
considerations we need to take into account.  i.e., is there
syncronization between code that has the BKL and llseek.

At the same time we remove the BKL it would be a good idea to do indicate
when no llseek function is required, so we don't have to revisit this code
again, when we are trying to determine if we can remove the BKL from the
default_llseek.

rtc: Remove BKL from efirtc

2009-10-14T15:36:51+00:00

BKL locking came to efirtc via the big BKL push down, but the access
to the efi functions is protected by efi_rtc_lock already.

Remove it.

efirtc: push down the BKL

2008-07-25T17:53:43+00:00

Push it down as far as the EFI method calls.  Someone who knows EFI can do
the other bits.  Also fix another wrong unknown ioctl return.
