* btrfs: Fix up 32/64-bit compatibility for new ioctlsJeff Mahoney2011-11-201-1/+1
| | | | | | | | | | | | | | This patch casts to unsigned long before casting to a pointer and fixes the following warnings: fs/btrfs/extent_io.c:2289:20: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] fs/btrfs/ioctl.c:2933:37: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] fs/btrfs/ioctl.c:2937:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] fs/btrfs/ioctl.c:3020:21: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] fs/btrfs/scrub.c:275:4: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] fs/btrfs/backref.c:686:27: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] Signed-off-by: Jeff Mahoney <jeffm@suse.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
* Btrfs: fix the new inspection ioctls for 32 bit compatChris Mason2011-11-061-4/+4
| | | | | | | | The new ioctls to follow backrefs are not clean for 32/64 bit compat. This reworks them for u64s everywhere. They are brand new, so there are no problems with changing the interface now. Signed-off-by: Chris Mason <chris.mason@oracle.com>
* btrfs: added helper functions to iterate backrefsJan Schmidt2011-09-291-0/+776
These helper functions iterate back references and call a function for each backref. There is also a function to resolve an inode to a path in the file system. Signed-off-by: Jan Schmidt <list.btrfs@jan-o-sch.net>
