kernel_read/kernel_write have always wrapped vfs_read/vfs_write, respectively, with a safety net around casting to user pointers too. kernel_read was always exported, going back to Linux's very first git check-in. kernel_write was exported in 3.9. Linux 4.14 unexported vfs_read & vfs_write, after replacing all modular calls to these functions with kernel_read & kernel_write, respectively. Linux 4.14 also changed the signatures of kernel_read & kernel_write to more closely match vfs_read & vfs_write. Signed-off-by: Pritam Baral <pritam@pritambaral.com>

Replaced by #667. @pritambaral thanks for refreshing this, I've taken your updated version and reworked it to be more strict about the prototypes. Can you please look it over. |
