* NTFS: Prepare for 2.1.23 release: Update documentation and bump version.Anton Altaparmakov2005-06-25
| | | | Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* 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
| | | | | | | | and ntfs_mapping_pairs_build() to allow the runlist encoding to be partial which is desirable when filling holes in sparse attributes. Update all callers. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* NTFS: Change the runlist terminator of the newly allocated cluster(s) toAnton Altaparmakov2005-06-25
| | | | | | | LCN_ENOENT in ntfs_attr_make_non_resident(). Otherwise the runlist code gets confused. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>
* NTFS: Fix several occurences of a bug where we would perform 'var & ~const'Anton Altaparmakov2005-06-25
| | | | | | | | with a 64-bit variable and a int, i.e. 32-bit, constant. This causes the higher order 32-bits of the 64-bit variable to be zeroed. To fix this cast the 'const' to the same 64-bit type as 'var'. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

* NTFS: Fix a bug in address space operations error recovery code paths whereAnton Altaparmakov2005-06-25
| | | | | | | | if the runlist was not mapped at all and a mapping error occured we would leave the runlist locked on exit to the function so that the next access to the same file would try to take the lock and deadlock. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

* NTFS: Some utilities modify the boot sector but do not update the checksum.Anton Altaparmakov2005-05-05
| | | | | | | | | Thus, relax the checking in fs/ntfs/super.c::is_boot_sector_ntfs() to only emit a warning when the checksum is incorrect rather than refusing the mount. Thanks to Bernd Casimir for pointing this problem out. Signed-off-by: Anton Altaparmakov <aia21@cantab.net>

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!
