What: mount/umount uevents
When: February 2007
Why: These events are not correct, and do not properly let userspace know
when a file system has been mounted or unmounted. Userspace should
poll the /proc/mounts file instead to detect this properly.

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.

- Write support is now extended with write(2) being able to both

@ -79,15 +79,27 @@ that instance in a system with many cpus making intensive use of it.
tmpfs has a mount option to set the NUMA memory allocation policy for
all files in that instance:
mpol=interleave prefers to allocate memory from each node in turn
mpol=default prefers to allocate memory from the local node
mpol=bind prefers to allocate from mpol_nodelist
mpol=preferred prefers to allocate from first node in mpol_nodelist
all files in that instance (if CONFIG_NUMA is enabled) - which can be
adjusted on the fly via 'mount -o remount ...'
The following mount option is used in conjunction with mpol=interleave,
mpol=bind or mpol=preferred:
mpol_nodelist: nodelist suitable for parsing with nodelist_parse.
mpol=default prefers to allocate memory from the local node
mpol=prefer:Node prefers to allocate memory from the given Node
mpol=bind:NodeList allocates memory only from nodes in NodeList
mpol=interleave prefers to allocate from each node in turn
mpol=interleave:NodeList allocates from each node of NodeList in turn
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
