Functions ¶

func CreateDeviceFile ¶

func CreateDeviceFile(ctx context.Context, vfsObj *vfs.VirtualFilesystem, creds *auth.Credentials, root vfs.VirtualDentry, pathname string, major, minor uint32, mode linux.FileMode, uid, gid *uint32) error

CreateDeviceFile creates a device special file at the given pathname from root.

Types ¶

type FilesystemType ¶

type FilesystemType struct{}

FilesystemType implements vfs.FilesystemType.

+stateify savable

func (FilesystemType) GetFilesystem ¶

func (fst FilesystemType) GetFilesystem(ctx context.Context, vfsObj *vfs.VirtualFilesystem, creds *auth.Credentials, source string, opts vfs.GetFilesystemOptions) (*vfs.Filesystem, *vfs.Dentry, error)

GetFilesystem implements vfs.FilesystemType.GetFilesystem.

func (FilesystemType) Name ¶

func (FilesystemType) Name() string

Name implements vfs.FilesystemType.Name.

func (*FilesystemType) Release ¶

func (fst *FilesystemType) Release(ctx context.Context)

Release implements vfs.FilesystemType.Release.

type InternalData ¶

type InternalData struct {
	// ShmMode indicates the mode to create the /dev/shm dir with.
	ShmMode *uint16
}

InternalData contains internal data passed in via vfs.GetFilesystemOptions.
