Hi all, Looking at the flags in the extent info, Is there any specifc flags which indicates an extent to be a HOLE?? I could only find the following ones... 39#define FIEMAP_MAX_OFFSET (~0ULL) 40 41#define FIEMAP_FLAG_SYNC 0x00000001 /* sync file data before map */ 42#define FIEMAP_FLAG_XATTR 0x00000002 /* map extended attribute tree */ 43 44#define FIEMAP_FLAGS_COMPAT (FIEMAP_FLAG_SYNC | FIEMAP_FLAG_XATTR) 45 46#define FIEMAP_EXTENT_LAST 0x00000001 /* Last extent in file. */ 47#define FIEMAP_EXTENT_UNKNOWN 0x00000002 /* Data location unknown. */ 48#define FIEMAP_EXTENT_DELALLOC 0x00000004 /* Location still pending. 49 * Sets EXTENT_UNKNOWN. */ 50#define FIEMAP_EXTENT_ENCODED 0x00000008 /* Data can not be read 51 * while fs is unmounted */ 52#define FIEMAP_EXTENT_DATA_ENCRYPTED 0x00000080 /* Data is encrypted by fs. 53 * Sets EXTENT_NO_BYPASS. */ 54#define FIEMAP_EXTENT_NOT_ALIGNED 0x00000100 /* Extent offsets may not be 55 * block aligned. */ 56#define FIEMAP_EXTENT_DATA_INLINE 0x00000200 /* Data mixed with metadata. 57 * Sets EXTENT_NOT_ALIGNED.*/ 58#define FIEMAP_EXTENT_DATA_TAIL 0x00000400 /* Multiple files in block. 59 * Sets EXTENT_NOT_ALIGNED.*/ 60#define FIEMAP_EXTENT_UNWRITTEN 0x00000800 /* Space allocated, but 61 * no data (i.e. zero). */ 62#define FIEMAP_EXTENT_MERGED 0x00001000 /* File does not natively 63 * support extents. Result 64 * merged for efficiency. */ -- Regards, Sandeep. “To learn is to change.
