Wong <darrick.wong@oracle.com> / #ifndef _LINUX_FSMAP_H #define _LINUX_FSMAP_H #include <linux/types.h> / * Structure for FS_IOC_GETFSMAP. * * The memory layout for this call are the scalar values defined in * struct fsmap_head, followed by two struct fsmap that describe * the lower and upper bound of mappings to return, followed by an * array of struct fsmap mappings. * * fmh_iflags control the output of the call, whereas fmh_oflags report * on the overall record output. fmh_count should be set to the * length of the fmh_recs array, and fmh_entries will be set to the * number of entries filled out during each call. If fmh_count is * zero, the number of reverse mappings will be returned in * fmh_entries, though no mappings will be returned. fmh_reserved * must be set to zero. * * The two elements in the fmh_keys array are used to constrain the * output. The first element in the array should represent the * lowest disk mapping ("low key") that the user wants to learn * about. If this value is all zeroes, the filesystem will return * the first entry it knows about. For a subsequent call, the * contents of fsmap_head.fmh_recs[fsmap_head.fmh_count - 1] should be * copied into fmh_keys[0] to have the kernel start where it left off. * * The second element in the fmh_keys array should represent the * highest disk mapping ("high key") that the user wants to learn * about. If this value is all ones, the filesystem will not stop * until it runs out of mapping to return or runs out of space in * fmh_recs. * * fmr_device can be either a 32-bit cookie representing a device, or * a 32-bit dev_t if the FMH_OF_DEV_T flag is set. fmr_physical, * fmr_offset, and fmr_length are expressed in units of bytes. * fmr_owner is either an inode number, or a special value if * FMR_OF_SPECIAL_OWNER is set in fmr_flags. / struct fsmap { __u32 fmr_device; / device id / __u32 fmr_flags; / mapping flags / __u64 fmr_physical; / device offset of segment / __u64 fmr_owner; / owner id / __u64 fmr_offset; / file offset of segment / __u64 fmr_length; / length of segment / __u64 fmr_reserved[3]; / must be zero / }; struct fsmap_head { __u32 fmh_iflags; / control flags / __u32 fmh_oflags; / output flags / __u32 fmh_count; / # of entries in array incl. input / __u32 fmh_entries; / # of entries filled in (output). / __u64 fmh_reserved[6]; / must be zero / struct fsmap fmh_keys[2]; / low and high keys for the mapping search / struct fsmap fmh_recs[]; / returned records / }; / Size of an fsmap_head with room for nr records. / static __inline__ size_t fsmap_sizeof( unsigned int nr) { return sizeof(struct fsmap_head) + nr sizeof(struct fsmap); } /* Start the next fsmap query at the end of the current query results. / static __inline__ void fsmap_advance( struct fsmap_head head) { head->fmh_keys[0] = head->fmh_recs[head->fmh_entries - 1]; } /* fmh_iflags values - set by FS_IOC_GETFSMAP caller in the header. / / no flags defined yet / #define FMH_IF_VALID 0 / fmh_oflags values - returned in the header segment only. / #define FMH_OF_DEV_T 0x1 / fmr_device values will be dev_t / / fmr_flags values - returned for each non-header segment / #define FMR_OF_PREALLOC 0x1 / segment = unwritten pre-allocation / #define FMR_OF_ATTR_FORK 0x2 / segment = attribute fork / #define FMR_OF_EXTENT_MAP 0x4 / segment = extent map / #define FMR_OF_SHARED 0x8 / segment = shared with another file / #define FMR_OF_SPECIAL_OWNER 0x10 / owner is a special value / #define FMR_OF_LAST 0x20 / segment is the last in the dataset / / Each FS gets to define its own special owner codes. / #define FMR_OWNER(type, code) (((__u64)type << 32) \| \ ((__u64)code & 0xFFFFFFFFULL)) #define FMR_OWNER_TYPE(owner) ((__u32)((__u64)owner >> 32)) #define FMR_OWNER_CODE(owner) ((__u32)(((__u64)owner & 0xFFFFFFFFULL))) #define FMR_OWN_FREE FMR_OWNER(0, 1) / free space / #define FMR_OWN_UNKNOWN FMR_OWNER(0, 2) / unknown owner / #define FMR_OWN_METADATA FMR_OWNER(0, 3) / metadata / #define FS_IOC_GETFSMAP _IOWR('X', 59, struct fsmap_head) #endif / _LINUX_FSMAP_H */
