CVE-2026-89618

In the Linux kernel, the following vulnerability has been resolved:

eventfs: Initialize ei->children and ei->list in init ei()

eventfs create dir() allocates the eventfs inode and initializes it with init ei(). But this does not initialize the eventfs inode list heads. If the eventfs create dir() fails due to memory pressure, it will call free ei() before it initialized the lists, and that checks to make sure the eventfs inode has no children. But because the list wasn't initialized, it will give a false warning.

Fix it by moving the list initialization into init ei().
