## Why `pgalloc()` is a syscall in a kernel build. It asserted the start of the break only in debug, and never the end, so a user task could map pages past `ARCH_ADDRENV_VEND`. ## How Return 0 for a break below the heap, unaligned, or with pages past the end of the address environment. ## Tested i.MX93, kernel build, a user task calling `pgalloc(0x100000000, 1)`, one page past `ARCH_ADDRENV_VEND`: | | result | | --- | --- | | before | mapped, returns `0x100000000` | | after | `0` | `tools/checkpatch.sh` clean. -- This is an automated message from the Apache Git Service.
