coccinelle: alloc_cast: drop removed allocatorsgrafted
- pci_alloc_consistent() and pci_zalloc_consistent() were removed by commit 7968778914e5 ("PCI: Remove the deprecated "pci-dma-compat.h" API") - kmem_alloc() was removed by commit f078d4ea8276 ("xfs: convert kmem_alloc() to kmalloc()") - kmem_zalloc() was removed by commit 10634530f7ba ("xfs: convert kmem_zalloc() to kzalloc()") - kmem_zone_alloc() and kmem_zone_zalloc() were removed by commit bae633a4a283 ("xfs: remove xfs_zone_{alloc,zalloc} helpers") So drop them from the rules. No functional change. Signed-off-by: Sang-Heon Jeon <ekffu200098@gmail.com> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr>

+What: /sys/block/loopX/loop/autoclear
+Date: Aug, 2010
+KernelVersion: v2.6.37
+Contact: linux-block@vger.kernel.org
+Description:
+ (RO) Shows if the device is in autoclear mode or not ( "1" or
+ "0"). Autoclear (if set) indicates that the loopback device will
+ self-distruct after last close.

+Description:
+ (RO) The path of the backing file that the loop device maps its
+ data blocks to.

+Description:
+ (RO) Shows if automatic partition scanning is enabled for the
+ device or not ("1" or "0"). This can be requested individually
+ per loop device during its setup by setting LO_FLAGS_PARTSCAN in
+ in the ioctl request. By default, no partition tables are
+ scanned.
