Analyze and fix the following issue in the Linux kernel code: fs: fix umask on NFS with CONFIG_FS_POSIX_ACL=n
Problem Details: Make IS_POSIXACL() return false if POSIX ACL support is disabled. Never skip applying the umask in namei.c and never bother to do any ACL specific checks if the filesystem falsely indicates it has ACLs enabled when the feature is completely disabled in the kernel. This fixes a problem where the umask...
