From 6383bdaa2ed2d461d9f4d369dfaa9d610fc972e3 Mon Sep 17 00:00:00 2001 From: Miklos Szeredi Date: Mon, 16 Jan 2006 22:14:29 -0800 Subject: [PATCH] [PATCH] fuse: miscellaneous cleanup - remove some unneeded assignments - use kzalloc instead of kmalloc + memset - simplify setting sb->s_fs_info - in fuse_send_init() use fuse_get_request() instead of do_get_request() helper Signed-off-by: Miklos Szeredi Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/fuse/dev.c | 4 ++-- fs/fuse/fuse_i.h | 7 +------ fs/fuse/inode.c | 10 +++------- 3 files changed, 6 insertions(+), 15 deletions(-) diff --git a/fs/fuse/dev.c b/fs/fuse/dev.c index d76432b757c9..4f1ca7b119ed 100644 --- a/fs/fuse/dev.c +++ b/fs/fuse/dev.c @@ -361,8 +361,8 @@ void request_send_background(struct fuse_conn *fc, struct fuse_req *req) void fuse_send_init(struct fuse_conn *fc) { /* This is called from fuse_read_super() so there's guaranteed - to be a request available */ - struct fuse_req *req = do_get_request(fc); + to be exactly one request available */ + struct fuse_req *req = fuse_get_request(fc); struct fuse_init_in *arg = &req->misc.init_in; arg->major = FUSE_KERNEL_VERSION; arg->minor = FUSE_KERNEL_MINOR_VERSION; diff --git a/fs/fuse/fuse_i.h b/fs/fuse/fuse_i.h index 74c8d098a14a..27937e8018eb 100644 --- a/fs/fuse/fuse_i.h +++ b/fs/fuse/fuse_i.h @@ -280,14 +280,9 @@ struct fuse_conn { struct backing_dev_info bdi; }; -static inline struct fuse_conn **get_fuse_conn_super_p(struct super_block *sb) -{ - return (struct fuse_conn **) &sb->s_fs_info; -} - static inline struct fuse_conn *get_fuse_conn_super(struct super_block *sb) { - return *get_fuse_conn_super_p(sb); + return sb->s_fs_info; } static inline struct fuse_conn *get_fuse_conn(struct inode *inode) diff --git a/fs/fuse/inode.c b/fs/fuse/inode.c index 04c80cc957a3..ceee75df7b32 100644 --- a/fs/fuse/inode.c +++ b/fs/fuse/inode.c @@ -200,9 +200,6 @@ static void fuse_put_super(struct super_block *sb) spin_lock(&fuse_lock); fc->mounted = 0; - fc->user_id = 0; - fc->group_id = 0; - fc->flags = 0; /* Flush all readers on this fs */ wake_up_all(&fc->waitq); up_write(&fc->sbput_sem); @@ -379,16 +376,15 @@ static struct fuse_conn *new_conn(void) { struct fuse_conn *fc; - fc = kmalloc(sizeof(*fc), GFP_KERNEL); + fc = kzalloc(sizeof(*fc), GFP_KERNEL); if (fc != NULL) { int i; - memset(fc, 0, sizeof(*fc)); init_waitqueue_head(&fc->waitq); INIT_LIST_HEAD(&fc->pending); INIT_LIST_HEAD(&fc->processing); INIT_LIST_HEAD(&fc->unused_list); INIT_LIST_HEAD(&fc->background); - sema_init(&fc->outstanding_sem, 0); + sema_init(&fc->outstanding_sem, 1); /* One for INIT */ init_rwsem(&fc->sbput_sem); for (i = 0; i < FUSE_MAX_OUTSTANDING; i++) { struct fuse_req *req = fuse_request_alloc(); @@ -420,7 +416,7 @@ static struct fuse_conn *get_conn(struct file *file, struct super_block *sb) fc = ERR_PTR(-EINVAL); } else { file->private_data = fc; - *get_fuse_conn_super_p(sb) = fc; + sb->s_fs_info = fc; fc->mounted = 1; fc->connected = 1; fc->count = 2; -- 2.20.1
