6.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: David Howells [ Upstream commit dbd6f56d975b23241b7bbb11bb8f562af548a0aa ] netfs_create_write_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 fscache_begin_write_operation() to be skipped. Fix this by removing the checks on the cookie and delegating this to fscache_begin_write_operation().
