[PATCH] Mark some key VFS functions as __always_inline
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)
