104 * Kernel shareable process resource limits. Because this structure
105 * is moderately large but changes infrequently, it is normally
106 * shared copy-on-write after forks. If a group of processes
107 * ("threads") share modifications, the PL_SHAREMOD flag is set,
108 * and a copy must be made for the child of a new fork that isn't
109 * sharing modifications to the limits.
112 * Modifications are done with the list lock held (p_limit as well)and access indv
113 * limits can be done without limit as we keep the old copy in p_olimit. Which is
114 * dropped in proc_exit. This way all access will have a valid kernel address
