@ -457,6 +457,12 @@ ChangeLog
Note, a technical ChangeLog aimed at kernel hackers is in fs/ntfs/ChangeLog.
2.1.26:
- Implement support for sector sizes above 512 bytes (up to the maximum
supported by NTFS which is 4096 bytes).
- Enhance support for NTFS volumes which were supported by Windows but
not by Linux due to invalid attribute list attribute flags.
- A few minor updates and bug fixes.
2.1.25:
- Write support is now extended with write(2) being able to both
overwrite existing file data and to extend files. Also, if a write

@ -92,6 +92,15 @@ NodeList format is a comma-separated list of decimal numbers and ranges,
a range being two hyphen-separated decimal numbers, the smallest and
largest node numbers in the range. For example, mpol=bind:0-3,5,7,9-15
Note that trying to mount a tmpfs with an mpol option will fail if the
running kernel does not support NUMA; and will fail if its nodelist
specifies a node >= MAX_NUMNODES. If your system relies on that tmpfs
being mounted, but from time to time runs a kernel built without NUMA
capability (perhaps a safe recovery kernel), or configured to support
fewer nodes, then it is advisable to omit the mpol option from automatic
mount options. It can be added later, when the tmpfs is already mounted
on MountPoint, by 'mount -o remount,mpol=Policy:NodeList MountPoint'.
To specify the initial root directory you can use the following mount
options:

help
Support the ACPI PM timer for time keeping. This is slow,
but is useful on some chipsets without HPET on systems with more
than one CPU. On a single processor or single socket multi core
system it is normally not required.
When the PM timer is active 64bit vsyscalls are disabled
and should not be enabled (/proc/sys/kernel/vsyscall64 should
not be changed).
The kernel selects the PM timer only as a last resort, so it is
useful to enable just in case.

making NTFS 1.2 specific modifications.
2.1.26 - Minor bug fixes and updates.
- Fix a potential overflow in file.c where a cast to s64 was missing in
a left shift of a page index.
- The struct inode has had its i_sem semaphore changed to a mutex named
i_mutex.
- We have struct kmem_cache now so use it instead of the typedef
kmem_cache_t. (Pekka Enberg)
- Implement support for sector sizes above 512 bytes (up to the maximum
supported by NTFS which is 4096 bytes).
- Do more detailed reporting of why we cannot mount read-write by
special casing the VOLUME_MODIFIED_BY_CHKDSK flag.
- Miscellaneous updates to layout.h.
- Cope with attribute list attribute having invalid flags. Windows
copes with this and even chkdsk does not detect or fix this so we
have to cope with it, too. Thanks to Pawel Kot for reporting the
problem.
