[patch 4/7] Mark some key VFS functions as __always_inline

From: Arjan van de Ven <arjan@infradead.org>

Mark a few VFS functions as mandatory inline (based on Al Viro's
request); these must be inline due to stack usage issues during a recursive loop
that happens during the recursive symlink resolution (symlink to a symlink to
a symlink ..)
This patch at this point does not change behavior and is for documentation purposes
only (but this changes later in the series)
