-//go:build raceattr
-
-// The raceattr program reproduces vfs inode file attribute race.
-//
-// Even though libfuse high-level API presents the address of a struct stat
-// alongside struct fuse_context, file attributes are actually inherent to the
-// inode, instead of the specific call from userspace. The kernel implementation
-// in fs/fuse/xattr.c appears to make stale data in the inode (set by a previous
-// call) impossible or very unlikely to reach userspace via the stat family of
-// syscalls. However, when using default_permissions to have the VFS check
-// permissions, this race still happens, despite the resulting struct stat being
-// correct when overriding the check via capabilities otherwise.
-//
-// This program reproduces the failure, but because of its continuous nature, it
-// is provided independent of the vm integration test suite.
