Coda has several advantages over NFS: support for + disconnected operation (e.g. for laptops), read/write server + replication, security model for authentication and encryption, + persistent client caches and write back caching. + + If you say Y here, your Linux box will be able to act as a Coda + *client*. You will need user level code as well, both for the + client and server. Servers are currently user level, i.e. they need + no kernel support. Please read + <file:Documentation/filesystems/coda.txt> and check out the Coda + home page <http://www.coda.cs.cmu.edu/>. + + To compile the coda client support as a module, choose M here: the + module will be called coda. diff --git a/fs/coda/file.c b/fs/coda/file.c index 466303db2df6..6a347fbc998a 100644 --- a/fs/coda/file.c +++ b/fs/coda/file.c @@ -201,8 +201,7 @@ int coda_release(struct inode *coda_inode, struct file *coda_file) int coda_fsync(struct file *coda_file, struct dentry *coda_dentry, int datasync) { struct file *host_file; - struct dentry *host_dentry; - struct inode *host_inode, *coda_inode = coda_dentry->d_inode; + struct inode *coda_inode = coda_dentry->d_inode; struct coda_file_info *cfi; int err = 0; @@ -214,14 +213,7 @@ int coda_fsync(struct file *coda_file, struct dentry *coda_dentry, int datasync) BUG_ON(!cfi || cfi->cfi_magic != CODA_MAGIC); host_file = cfi->cfi_container; - if (host_file->f_op && host_file->f_op->fsync) { - host_dentry = host_file->f_path.dentry; - host_inode = host_dentry->d_inode; - mutex_lock(&host_inode->i_mutex); - err = host_file->f_op->fsync(host_file, host_dentry, datasync); - mutex_unlock(&host_inode->i_mutex); - } - + err = vfs_fsync(host_file, host_file->f_path.dentry, datasync); if ( !err && !datasync ) { lock_kernel(); err = venus_fsync(coda_inode->i_sb, coda_i2f(coda_inode)); diff --git a/fs/coda/sysctl.c b/fs/coda/sysctl.c index 81b7771c6465..43c96ce29614 100644 --- a/fs/coda/sysctl.c +++ b/fs/coda/sysctl.c @@ -11,7 +11,9 @@ #include "coda_int.h" +#ifdef CONFIG_SYSCTL static struct ctl_table_header *fs_table_header; +#endif static ctl_table coda_table[] = { { @@ -41,6 +43,7 @@ static ctl_table coda_table[] = { {} }; +#ifdef CONFIG_SYSCTL static ctl_table fs_table[] = { { .ctl_name = CTL_UNNUMBERED, @@ -50,7 +53,7 @@ static ctl_table fs_table[] = { }, {} }; - +#endif void coda_sysctl_init(void) { |
