From: Arjan van de Ven Date: Sat, 14 Jan 2006 21:21:31 +0000 (-0800) Subject: [PATCH] Mark some key VFS functions as __always_inline X-Git-Tag: v2.6.16-rc1~110 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f16623569e2ec055b489462315f5296f153d119b;p=linux-2.6 [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 Signed-off-by: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- diff --git a/fs/namei.c b/fs/namei.c index 7bde381fa4..33fb5bd34a 100644 --- a/fs/namei.c +++ b/fs/namei.c @@ -486,7 +486,7 @@ static struct dentry * real_lookup(struct dentry * parent, struct qstr * name, s static int __emul_lookup_dentry(const char *, struct nameidata *); /* SMP-safe */ -static inline int +static __always_inline int walk_init_root(const char *name, struct nameidata *nd) { read_lock(¤t->fs->lock); @@ -504,7 +504,7 @@ walk_init_root(const char *name, struct nameidata *nd) return 1; } -static inline int __vfs_follow_link(struct nameidata *nd, const char *link) +static __always_inline int __vfs_follow_link(struct nameidata *nd, const char *link) { int res = 0; char *name; @@ -544,7 +544,7 @@ struct path { struct dentry *dentry; }; -static inline int __do_follow_link(struct path *path, struct nameidata *nd) +static __always_inline int __do_follow_link(struct path *path, struct nameidata *nd) { int error; void *cookie; @@ -690,7 +690,7 @@ int follow_down(struct vfsmount **mnt, struct dentry **dentry) return 0; } -static inline void follow_dotdot(struct nameidata *nd) +static __always_inline void follow_dotdot(struct nameidata *nd) { while(1) { struct vfsmount *parent;
