NAME¶
vfs_link - create a new linkSYNOPSIS¶
int
vfs_link(struct dentry * old_dentry,
struct inode * dir,
struct dentry * new_dentry,
struct inode ** delegated_inode);
ARGUMENTS¶
old_dentryobject to be linked
dir
new parent
new_dentry
where to create the new link
delegated_inode
returns inode needing a delegation break
DESCRIPTION¶
The caller must hold dir->i_mutex If vfs_link discovers a delegation on the to-be-linked file in need of breaking, it will return -EWOULDBLOCK and return a reference to the inode in delegated_inode. The caller should then break the delegation and retry. Because breaking a delegation may take a long time, the caller should drop the i_mutex before doing so. Alternatively, a caller may pass NULL for delegated_inode. This may be appropriate for callers that expect the underlying filesystem not to be NFS exported.COPYRIGHT¶
