existence, and all types of systems in between. It is a robust, efficient,

Ioctls
|
||||
======
|
||||
|
||||
There is some Ext4 specific functionality which can be accessed by applications
|
||||
through the system call interfaces. The list of all Ext4 specific ioctls are
|
||||
shown in the table below.
|
||||
|
||||
Table of Ext4 specific ioctls
|
||||
..............................................................................
|
||||
Ioctl Description
|
||||
EXT4_IOC_GETFLAGS Get additional attributes associated with inode.
|
||||
The ioctl argument is an integer bitfield, with
|
||||
bit values described in ext4.h. This ioctl is an
|
||||
alias for FS_IOC_GETFLAGS.
|
||||
|
||||
EXT4_IOC_SETFLAGS Set additional attributes associated with inode.
|
||||
The ioctl argument is an integer bitfield, with
|
||||
bit values described in ext4.h. This ioctl is an
|
||||
alias for FS_IOC_SETFLAGS.
|
||||
|
||||
EXT4_IOC_GETVERSION
|
||||
EXT4_IOC_GETVERSION_OLD
|
||||
Get the inode i_generation number stored for
|
||||
each inode. The i_generation number is normally
|
||||
changed only when new inode is created and it is
|
||||
particularly useful for network filesystems. The
|
||||
'_OLD' version of this ioctl is an alias for
|
||||
FS_IOC_GETVERSION.
|
||||
|
||||
EXT4_IOC_SETVERSION
|
||||
EXT4_IOC_SETVERSION_OLD
|
||||
Set the inode i_generation number stored for
|
||||
each inode. The '_OLD' version of this ioctl
|
||||
is an alias for FS_IOC_SETVERSION.
|
||||
|
||||
EXT4_IOC_GROUP_EXTEND This ioctl has the same purpose as the resize
|
||||
mount option. It allows to resize filesystem
|
||||
to the end of the last existing block group,
|
||||
further resize has to be done with resize2fs,
|
||||
either online, or offline. The argument points
|
||||
to the unsigned logn number representing the
|
||||
filesystem new block count.
|
||||
|
||||
EXT4_IOC_MOVE_EXT Move the block extents from orig_fd (the one
|
||||
this ioctl is pointing to) to the donor_fd (the
|
||||
one specified in move_extent structure passed
|
||||
as an argument to this ioctl). Then, exchange
|
||||
inode metadata between orig_fd and donor_fd.
|
||||
This is especially useful for online
|
||||
defragmentation, because the allocator has the
|
||||
opportunity to allocate moved blocks better,
|
||||
ideally into one contiguous extent.
|
||||
|
||||
EXT4_IOC_GROUP_ADD Add a new group descriptor to an existing or
|
||||
new group descriptor block. The new group
|
||||
descriptor is described by ext4_new_group_input
|
||||
structure, which is passed as an argument to
|
||||
this ioctl. This is especially useful in
|
||||
conjunction with EXT4_IOC_GROUP_EXTEND,
|
||||
which allows online resize of the filesystem
|
||||
to the end of the last existing block group.
|
||||
Those two ioctls combined is used in userspace
|
||||
online resize tool (e.g. resize2fs).
|
||||
|
||||
EXT4_IOC_MIGRATE This ioctl operates on the filesystem itself.
|
||||
It converts (migrates) ext3 indirect block mapped
|
||||
inode to ext4 extent mapped inode by walking
|
||||
through indirect block mapping of the original
|
||||
inode and converting contiguous block ranges
|
||||
into ext4 extents of the temporary inode. Then,
|
||||
inodes are swapped. This ioctl might help, when
|
||||
migrating from ext3 to ext4 filesystem, however
|
||||
suggestion is to create fresh ext4 filesystem
|
||||
and copy data from the backup. Note, that
|
||||
filesystem has to support extents for this ioctl
|
||||
to work.
|
||||
|
||||
EXT4_IOC_ALLOC_DA_BLKS Force all of the delay allocated blocks to be
|
||||
allocated to preserve application-expected ext3
|
||||
behaviour. Note that this will also start
|
||||
triggering a write of the data blocks, but this
|
||||
behaviour may change in the future as it is
|
||||
not necessary and has been done this way only
|
||||
for sake of simplicity.

The Extended Industry Standard Architecture (EISA) bus was

developed as an open alternative to the IBM MicroChannel bus.
|

|
||||
The EISA bus provided some of the features of the IBM MicroChannel
|
||||
bus while maintaining backward compatibility with cards made for
|
||||
the older ISA bus. The EISA bus saw limited use between 1988 and
|
||||
1995 when it was made obsolete by the PCI bus.
|
||||
|

Say Y here if you are building a kernel for an EISA-based machine.
|
||||
|

Otherwise, say N.

Copyback caching means that memory writes will be held in an on-chip
