[PATCH RESEND] fs/buffer.c: include fs/internal.h for missing prototypes

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

__block_write_begin_int(), __generic_write_end(), and guard_bio_eod()
are defined in fs/buffer.c and declared in fs/internal.h, but the
declarations aren't included at the point of the definitions.  Include
the header to enforce that the definitions match the declarations.

This addresses gcc warnings when -Wmissing-prototypes is enabled.

Ping.  Al, are you planning to apply this?

[PATCH RESEND] fs/buffer.c: include fs/internal.h for missing prototypes

[Eric Biggers]

From: Eric Biggers <ebiggers@google.com>

Include fs/internal.h to address the following 'sparse' warnings:

    fs/buffer.c:1930:5: warning: symbol '__block_write_begin_int' was not declared. Should it be static?
    fs/buffer.c:2089:6: warning: symbol '__generic_write_end' was not declared. Should it be static?
    fs/buffer.c:2998:6: warning: symbol 'guard_bio_eod' was not declared. Should it be static?
