Field Documentation

lle_base

struct m0_layout_enum lle_base

Super class.

Definition at line 48 of file list_enum.h.

lle_list_of_cobs

struct m0_fid* lle_list_of_cobs

Pointer to an array of COB identifiers for the component objects which are part of 'the layout this enum is assocaited with'.

Todo:

In kernel any allocation over 4KB is not safe. Thus, this array can safely hold only upto 256 number of COB identifiers, (m0_fid being 16 bytes in size). This issue is to be addressed later.
