Hans Petter Selasky 56c49c63e7 Allow CUSE(3) to free all memory mapped memory by using regular SWAP objects ... instead of malloc(). The SWAP objects are automagically freed when there are no more consumers. This greatly simplifies the mmap logic inside CUSE(3) in the kernel. This change fixes an issue where mmapped memory can accumulate and never get freed, if many different mmap sizes are needed over time. Further this change fixes memory leaks when the CUSE(3) kernel module is unloaded. While at it make sure the CUSE_ALLOC_PAGES_MAX limit is treated as an exclusive limit. CUSE(3) memory maps must be less than CUSE_ALLOC_PAGES_MAX number of pages.
