Subject: Linux: Pass size argument of epoll_create to the kernel
X-Git-Tag: glibc-2.37~61

Linux: Pass size argument of epoll_create to the kernel

The kernel actually verifies it, and a garbage value in the register
causes improper system call failures.

Fixes commit c1c0dea38833751f36a145c32 ("Linux: Remove epoll_create,
inotify_init from syscalls.list") and commit d1d23b134244d59c4d6ef2295
("Lninux: consolidate epoll_create implementation").
