[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) Signed-off-by: Arjan van de Ven <arjan@infradead.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
