This would fix the "logical_block" string as well since it should be either "logical block" or "block number". > > errcode = ext2fs_bmap2(current_fs, ino, 0, 0, 0, blk, 0, &pblk); > if (errcode) { > @@ -2195,9 +2196,9 @@ void do_punch(int argc, char *argv[]) > ino = string_to_inode(argv[1]); > if (!ino) > return; > - start = parse_ulong(argv[2], argv[0], "logical_block", &err); > + start = parse_ulonglong(argv[2], argv[0], "logical_block", &err); > if (argc == 4) > - end = parse_ulong(argv[3], argv[0], "logical_block", &err); > + end = parse_ulonglong(argv[3], argv[0], "logical_block", &err); > else > end = ~0; > > @@ -2415,8 +2416,8 @@ int main(int argc, char **argv) > "block size", 0); > break; > case 's': > - superblock = parse_ulong(optarg, argv[0], > - "superblock number", 0); > + superblock = parse_ulonglong(optarg, argv[0], > + "superblock number", 0); same here Thanks! -Lukas > break; > case 'c': > catastrophic = 1; > diff --git a/debugfs/extent_inode.c b/debugfs/extent_inode.c > index 0bbc4c5..d5c4721 100644 > --- a/debugfs/extent_inode.c > +++ b/debugfs/extent_inode.c > @@ -264,7 +264,8 @@ void do_replace_node(int argc, char *argv[]) > return; > } > > - extent.e_lblk = parse_ulong(argv[1], argv[0], "logical block", &err); > + extent.e_lblk = parse_ulonglong(argv[1], argv[0], "logical block", > + &err); > if (err) > return; > > @@ -272,7 +273,8 @@ void do_replace_node(int argc, char *argv[]) > if (err) > return; > > - extent.e_pblk = parse_ulong(argv[3], argv[0], "logical block", &err); > + extent.e_pblk = parse_ulonglong(argv[3], argv[0], "logical block", > + &err); > if (err) > return; > > @@ -338,8 +340,8 @@ void do_insert_node(int argc, char *argv[]) > return; > } > > - extent.e_lblk = parse_ulong(argv[1], cmd, > - "logical block", &err); > + extent.e_lblk = parse_ulonglong(argv[1], cmd, > + "logical block", &err); > if (err) > return; > > @@ -348,8 +350,8 @@ void do_insert_node(int argc, char *argv[]) > if (err) > return; > > - extent.e_pblk = parse_ulong(argv[3], cmd, > - "pysical block", &err); > + extent.e_pblk = parse_ulonglong(argv[3], cmd, > + "physical block", &err); > if (err) > return; > > @@ -366,8 +368,8 @@ void do_set_bmap(int argc, char **argv) > const char *usage = "[--uninit] <lblk> <pblk>"; > struct ext2fs_extent extent; > errcode_t retval; > - blk_t logical; > - blk_t physical; > + blk64_t logical; > + blk64_t physical; > char *cmd = argv[0]; > int flags = 0; > int err; > @@ -387,18 +389,18 @@ void do_set_bmap(int argc, char **argv) > return; > } > > - logical = parse_ulong(argv[1], cmd, > + logical = parse_ulonglong(argv[1], cmd, > "logical block", &err); > if (err) > return; > > - physical = parse_ulong(argv[2], cmd, > + physical = parse_ulonglong(argv[2], cmd, > "physical block", &err); > if (err) > return; > > retval = ext2fs_extent_set_bmap(current_handle, logical, > - (blk64_t) physical, flags); > + physical, flags); > if (retval) { > com_err(cmd, retval, 0); > return; > diff --git a/debugfs/util.c b/debugfs/util.c > index cf3a6c6..245d556 100644 > --- a/debugfs/util.c > +++ b/debugfs/util.c > @@ -377,7 +377,7 @@ int common_block_args_process(int argc, char *argv[], > } > > if (argc > 2) { > - *count = parse_ulong(argv[2], argv[0], "count", &err); > + *count = parse_ulonglong(argv[2], argv[0], "count", &err); > if (err) > return 1; > } > > -- > To unsubscribe from this list: send the line "unsubscribe linux-ext4" in > the body of a message to majordomo@...r.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
