From: Kees Cook <keescook@chromium.org> stable inclusion from stable-5.10 category: feature commit:47af61ffb19baa8df2b109582f87f7622fbe85cc issue: #I4919J -------------------------------- The name "allpstore" doesn't carry much meaning, so rename it to what it actually is: the list of all records present in the filesystem. The lock is also renamed accordingly.
