kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
