e3fa34681b Convert mqueue structure for use in VFS as inode data; rename mqueue_inode_s; remove links, reference counts and name from mqueue structure. These will be replaced by VFS data. Remove g_msgqueues and mq_findnamed.c; these will be replace with VFS logic 2014-09-29 13:19:11 -06:00

835c91b03a Add support for a per-process virtual page allocator. This is a new member of the task_group_s structure. The allocaor must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory. 2014-09-23 16:04:39 -06:00

31824f5b53 execl() is not a system interface. It belongs in libc and should not have a system call associated with it. 2014-09-15 10:17:04 -06:00

da7a440b35 execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symboltable helper logic also belongs in the kernel but belings in binfmt/ with the other symbol table logic 2014-09-15 10:15:19 -06:00
