1UpstreamStatus: Inappropriate
2
3This patch fixes populated dosfs image creation with directory
4structures. Earlier it was causing segfault; and only image
5population with no subdirectories was working.
6
7Issues fixed:
81. (dir->count == dir->entries) check was only needed for root
9 directory entries. And this check is wrong for non-root
10 directories.
112. For each dir entry 2 dir->table entries were needed, one for
12 the file/dir and 2nd for long file name support. Earlier long
13 name support was added for filenames but the 2nd entry
14 allocation, initialization & counting was missed.
153. The memory clearing was missed at the code path after dir->table
16 memroy allocation.
174. Add entries for . & .. directories in all non-root directories.
185. The . directory points to the correct entry in fat now.
196. All directoriy entries' size was not zero as required for dosfsck,
20 Now all directory entries' size is zero.
21
22Enhancements:
231. Added support for long names for directory names. This is same
24 as the existing long name support for filenames.
252. Added error messages for previously silent memory allocation and
26 other errors.
273. -d options does not work correctly with fat32, so now throwing
28 an error for that.
294. Use predefined structures from kernel's msdos_fs.h file, rather
30 than defining again here. And accordingly change the names & use
31 of structure variables.
32
33Outstanding Issues:
341. The .. directory entry do not point to the parent of current
35 directory. This issue can be fixed by running dosfsck -a after
36 image creation.
372. For files the filesize is correct, but the clusters size is more
38 than it needs to be, this also can be fixed by running dosfsck -a
39 after image creation.

56+ Enhanced the -d <directory> support for population of image while
57+ creation. Earlier subdirectores support was broken, only files in
58+ the rootdir were supported. Now directory hirarchy is supported.
59+ Also added long filename support to directory names.
60+ The -d <directory> option (image population while creation)
61+ is broken with fat32.
