CVE-2026-72366

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

netfs: Fix netfscreatewrite_req() to handle async cache object creation

netfscreatewrite_req() will skip caching if the fscache cookie is

disabled, but this is a problem because async cache object creation might

not have got far enough yet that has been enabled - thereby causing the

call to fscachebeginwrite_operation() to be skipped.

Fix this by removing the checks on the cookie and delegating this to

fscachebeginwrite_operation().
