VFS_UNLINK(9) | The Linux VFS | VFS_UNLINK(9) |
NAME¶
vfs_unlink - unlink a filesystem object
SYNOPSIS¶
int vfs_unlink(struct inode * dir, struct dentry * dentry, struct inode ** delegated_inode);
ARGUMENTS¶
struct inode * dir
struct dentry * dentry
struct inode ** delegated_inode
DESCRIPTION¶
The caller must hold dir->i_mutex.
If vfs_unlink discovers a delegation, it will return -EWOULDBLOCK and return a reference to the inode in delegated_inode. The caller should then break the delegation on that inode and retry. Because breaking a delegation may take a long time, the caller should drop dir->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.
