Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
2.0.24:
- Small internal cleanups.
- Support for sendfile system call. (Christoph Hellwig)
2.0.23:
- Massive internal locking changes to mft record locking. Fixes
various race conditions and deadlocks.
- Fix ntfs over loopback for compressed files by adding an
optimization barrier. (gcc was screwing up otherwise ?)
Thanks go to Christoph Hellwig for pointing these two out:
- Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
- Fix ntfs_free() for ia64 and parisc.
2.0.22:
- Small internal cleanups.
2.0.21:

View file @ b14ebcfc
......@@ -2,6 +2,36 @@ ToDo:
- Find and fix bugs.
- Enable NFS exporting of NTFS.
2.0.24 - Cleanups.
- Treat BUG_ON() as ASSERT() not VERIFY(), i.e. do not use side effects
inside BUG_ON(). (Adam J. Richter)
- Split logical OR expressions inside BUG_ON() into individual BUG_ON()
calls for improved debugging. (Adam J. Richter)
- Add errors flag to the ntfs volume state, accessed via
NVol{,Set,Clear}Errors(vol).
- Do not allow read-write remounts of read-only volumes with errors.
- Clarify comment for ntfs file operation sendfile which was added by
Christoph Hellwig a while ago (just using generic_file_sendfile())
to say that ntfs ->sendfile is only used for the case where the
source data is on the ntfs partition and the destination is
somewhere else, i.e. nothing we need to concern ourselves with.
- Add generic_file_write() as our ntfs file write operation.
2.0.23 - Major bug fixes (races, deadlocks, non-i386 architectures).
- Massive internal locking changes to mft record locking. Fixes lock
recursion and replaces the mrec_lock read/write semaphore with a
mutex. Also removes the now superfluous mft_count. This fixes several
race conditions and deadlocks, especially in the future write code.
- Fix ntfs over loopback for compressed files by adding an
optimization barrier. (gcc was screwing up otherwise ?)
- Miscellaneous cleanups all over the code and a fix or two in error
handling code paths.
Thanks go to Christoph Hellwig for pointing out the following two:
- Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
- Fix ntfs_free() for ia64 and parisc by checking for VMALLOC_END, too.
2.0.22 - Cleanups, mainly to ntfs_readdir(), and use C99 initializers.
- Change fs/ntfs/dir.c::ntfs_reddir() to only read/write ->f_pos once
