Subject: [PATCH 2/2] ima: evm: Rename *_post_path_mknod() to *_path_post_mknod()

From: Roberto Sassu <roberto.sassu@...wei.com>

Rename ima_post_path_mknod() and evm_post_path_mknod() respectively to
ima_path_post_mknod() and evm_path_post_mknod(), to facilitate finding
users of the path_post_mknod LSM hook.

Cc: stable@...r.kernel.org # 6.8.x
Reported-by: Christian Brauner <christian@...uner.io>
Closes: https://lore.kernel.org/linux-kernel/20240328-raushalten-krass-cb040068bde9@brauner/
Fixes: 05d1a717ec04 ("ima: add support for creating files using the mknodat syscall")
Fixes: cd3cec0a02c7 ("ima: Move to LSM infrastructure")
Signed-off-by: Roberto Sassu <roberto.sassu@...wei.com>
