generic_shutdown_super —
common helper for ->kill_sb
void generic_shutdown_super ( | struct super_block * sb); |
generic_shutdown_super does all fs-independent work on superblock
shutdown. Typical ->kill_sb should pick all fs-specific objects
that need destruction out of superblock, call generic_shutdown_super
and release aforementioned objects. Note: dentries and inodes _are_
taken care of and do not need specific handling.
Upon calling this function, the filesystem may no longer alter or rearrange the set of dentries belonging to this super_block, nor may it change the attachments of dentries to inodes.
