[klibc] [BUG][PATCH] fstype: wrong size returned for jfs
[please note that I'm not subscribed to the list] Hi guys, I've noticed that the size returned by the fstype utility was not correct for JFS filesystems (it returns the size in number of HW blocks instead of bytes). Here is a simple patch that addresses it (based on 1.5.7 from the debian package). diff -Nur klibc-1.5.7.orig/usr/kinit/fstype/fstype.c klibc-1.5.7/usr/kinit/fstype/fstype.c --- klibc-1.5.7.orig/usr/kinit/fstype/fstype.c 2007-09-04 09:17:12.000000000 +0100 +++ klibc-1.5.7/usr/kinit/fstype/fstype.c 2008-03-03 16:57:34.522813138 +0000 @@ -205,7 +205,7 @@ const struct jfs_superblock *sb = (const struct jfs_superblock *)buf; if (!memcmp(sb->s_magic, JFS_MAGIC, 4)) { - *bytes = __le32_to_cpu(sb->s_size); + *bytes = __le64_to_cpu(sb->s_size) << __le16_to_cpu(sb->s_l2pbsize); return 1; } return 0; HTH, Stephane
