[patch 4.19.6 1/2] BFS static inode bitmap allocation

Hi Linus,

As per Greg's instructions, this is part 1 of the set of 2 patches. This patch switches inode bitmap allocation to static. The whole set differs from what went into Andrew Morton's trees only by the trivial cleanup (whitespace etc) which is, according to the rules, not appropriate for the stable Linux kernel, hence not included in the set.

The second part will follow in a minute as a separate email.

Kind regards, Tigran
