SubjectAdding a field to ext2_dir_entry_2
From
Date



Hi All,



I working with linux kernel 2.4.28. I want to add 1 more field to ext2_dir_entry_2 - the new version of directory entry for ext2fs.



I did add the __u32 field to the struct ext2_dir_entry_2 defined in ext2_fs.h I also modified the EXT2_DIR_REC_LEN macro to:



(((name_len) + 12 + EXT2_DIR_ROUND) & ~EXT2_DIR_ROUND)



(+12 instead of +8) to incorporate newly added 4 bytes field.



I made the similar changes to the mke2fs utility also.



When I try to copy a file on that file system, I am getting the following error:



"ext2-fs error (device fd(2,0)): ext2_check_page: bad entry in directory #2: unaligned directory entry - offset=0, inode=2, rec_len=46, name_len=0"



Can someone please tell me where am I going wrong or what other changes do I need to do to add the field I want?



Thanks and regards,



Vineet Joglekar
