This is an implementation of the shared memory support that uses a linked list, instead of a static array.

This directory contains the files with the alternate implementation of System V shared memory, using a linked list:

• ipc/shm.c
• include/linux/shm.h

It also has a set of test programs:

• test1.c creates (if necessary) and attaches to a shared memory segment; it then reads from it every 5 secs
• test2.c attaches to an existing segment, and writes to it (every 3 secs)
• test3.c removes a segment, if there is no process attached

I did not stress the list-based shm implementation to check that it conforms to POSIX specs.

include/linux/shm.h the new shared memory declarations
ipc/shm.c the new shared memory implementation
test1.c
test2.c
