From: arnd@arndb.de (Arnd Bergmann)
Date: 2015-12-10 15:10:48
Also in:
linux-unionfs, lkml
Subsystem:
filesystems (vfs and infrastructure), overlay filesystem, the rest · Maintainers:

The overlayfs has started enforcing a maximum file size, but is missing
the header file that defines the PAGE_CACHE_SIZE constant in some
configurations.
fs/overlayfs/super.c: In function 'ovl_fill_super':
fs/overlayfs/super.c:939:29: error: 'PAGE_CACHE_SIZE' undeclared (first use in this function)

The patch that introduced this was marked for stable, so I'm marking this
