- Enable the code for setting the NT4 compatibility flag when we start
making NTFS 1.2 specific modifications.
-2.1.24-WIP
+2.1.24 - Lots of bug fixes and support more clean journal states.
- Support journals ($LogFile) which have been modified by chkdsk. This
means users can boot into Windows after we marked the volume dirty.
The Windows boot will run chkdsk and then reboot. The user can then
immediately boot into Linux rather than having to do a full Windows
boot first before rebooting into Linux and we will recognize such a
- journal and empty it as it is clean by definition.
+ journal and empty it as it is clean by definition. Note, this only
+ works if chkdsk left the journal in an obviously clean state.
- Support journals ($LogFile) with only one restart page as well as
journals with two different restart pages. We sanity check both and
either use the only sane one or the more recent one of the two in the
case that both are valid.
- - Modify fs/ntfs/malloc.h::ntfs_malloc_nofs() to do the kmalloc() based
- allocations with __GFP_HIGHMEM, analogous to how the vmalloc() based
- allocations are done.
- Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
hence cannot fail.
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.
+ - Fix handling of sparse attributes in ntfs_attr_make_non_resident().
+ - 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.
+ - Fix cluster (de)allocators to work when the runlist is NULL and more
+ importantly to take a locked runlist rather than them locking it
+ which leads to lock reversal.
+ - Truncate {a,c,m}time to the ntfs supported time granularity when
+ updating the times in the inode in ntfs_setattr().
+ - Fixup handling of sparse, compressed, and encrypted attributes in
+ fs/ntfs/inode.c::ntfs_read_locked_{,attr_,index_}inode(),
+ fs/ntfs/aops.c::ntfs_{read,write}page().
+ - Make ntfs_write_block() not instantiate sparse blocks if they contain
+ only zeroes.
+ - Optimize fs/ntfs/aops.c::ntfs_write_block() by extending the page
+ lock protection over the buffer submission for i/o which allows the
+ removal of the get_bh()/put_bh() pairs for each buffer.
+ - Fix fs/ntfs/aops.c::ntfs_{read,write}_block() to handle the case
+ where a concurrent truncate has truncated the runlist under our feet.
+ - Fix page_has_buffers()/page_buffers() handling in fs/ntfs/aops.c.
+ - In fs/ntfs/aops.c::ntfs_end_buffer_async_read(), use a bit spin lock
+ in the first buffer head instead of a driver global spin lock to
+ improve scalability.
+ - Minor fix to error handling and error message display in
+ fs/ntfs/aops.c::ntfs_prepare_nonresident_write().
+ - Change the mount options {u,f,d}mask to always parse the number as
+ an octal number to conform to how chmod(1) works, too. Thanks to
+ Giuseppe Bilotta and Horst von Brand for pointing out the errors of
+ my ways.
+ - Fix various bugs in the runlist merging code. (Based on libntfs
+ changes by Richard Russon.)
+ - Fix sparse warnings that have crept in over time.
+ - Change ntfs_cluster_free() to require a write locked runlist on entry
+ since we otherwise get into a lock reversal deadlock if a read locked
+ runlist is passed in. In the process also change it to take an ntfs
+ inode instead of a vfs inode as parameter.
+ - Fix the definition of the CHKD ntfs record magic. It had an off by
+ two error causing it to be CHKB instead of CHKD.
+ - Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
+ count to become negative and hence we had a wild memset() scribbling
+ all over the system's ram.
2.1.23 - Implement extension of resident files and make writing safe as well as
many bug fixes, cleanups, and enhancements...
