NAME¶

deactivate_locked_super - drop an active reference to superblock

SYNOPSIS¶

void deactivate_locked_super(struct super_block * s);

ARGUMENTS¶

s

DESCRIPTION¶

Equivalent of up_write(s->s_umount); deactivate_super(s);, except that it does not unlock it until it´s all over. As the result, it´s safe to use to dispose of new superblock on ->get_sb failure exits - nobody will see the sucker until it´s all over. Equivalent using up_write + deactivate_super is safe for that purpose only if superblock is either safe to use or has NULL ->s_root when we unlock.
