* NTFS: Fix handling of sparse attributes in ntfs_attr_make_non_resident().Anton Altaparmakov2005-09-08
| | | | | | | | Also, add BUG() checks to ntfs_attr_make_non_resident() and ntfs_attr_set() to ensure that these functions are never called for compressed or encrypted attributes. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* NTFS: Fix several bugs in fs/ntfs/attrib.c.Anton Altaparmakov2005-09-08
| | | | | | | | | | | - Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect access to the allocated size in the ntfs inode with the size lock. - Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to return LCN_ENOENT when there is no runlist and the allocated size is zero. - Fix load_attribute_list() to handle the case of a NULL runlist.

* NTFS: Change ntfs_map_runlist_nolock() to only decompress the mapping pairsAnton Altaparmakov2005-06-25
| | | | | | | | | | if the requested vcn is inside it. Otherwise we get into problems when we try to map an out of bounds vcn because we then try to map the already mapped runlist fragment which causes ntfs_mapping_pairs_decompress() to fail and return error. Update ntfs_attr_find_vcn_nolock() accordingly. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* NTFS: Add an extra parameter @last_vcn to ntfs_get_size_for_mapping_pairs()Anton Altaparmakov2005-06-25

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
