[PATCH] fs: include internal.h for missing declarations

[Ben Dooks]

The declarations of __block_write_begin_int and guard_bio_eod
are needed from internal.h so include it to fix 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:2994:6: warning: symbol 'guard_bio_eod' was not declared. Should it be static?
