[PATCH] fat: add fat_getattr()

2006-11-16T19:43:38+00:00

This adds fat_getattr() for setting stat->blksize. (FAT uses the size
of cluster for proper I/O)

[PATCH] separate bdi congestion functions from queue congestion functions

2006-10-20T17:26:35+00:00

Separate out the concept of "queue congestion" from "backing-dev congestion".
Congestion is a backing-dev concept, not a queue concept.

The blk_* congestion functions are retained, as wrappers around the core
backing-dev congestion functions.

This proper layering is needed so that NFS can cleanly use the congestion
functions, and so that CONFIG_BLOCK=n actually links.

[PATCH] Remove unnecessary check in fs/fat/inode.c

2006-10-11T18:14:23+00:00

Aince all callers dereference sb, and this function does so earlier too, we
dont need the check.

[PATCH] VFS: Make filldir_t and struct kstat deal in 64-bit inode numbers

2006-10-03T15:03:40+00:00

These patches make the kernel pass 64-bit inode numbers internally when
communicating to userspace, even on a 32-bit system.  They are required
because some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS
for example.  The 64-bit inode numbers are then propagated to userspace
automatically where the arch supports it.

Problems have been seen with userspace (eg: ld.so) using the 64-bit inode
number returned by stat64() or getdents64() to differentiate files, and
failing because the 64-bit inode number space was compressed to 32-bits, and
so overlaps occur.

This patch:

Make filldir_t take a 64-bit inode number and struct kstat carry a 64-bit
inode number so that 64-bit inode numbers can be passed back to userspace.

The stat functions then returns the full 64-bit inode number where
available and where possible.  If it is not possible to represent the inode
number supplied by the filesystem in the field provided by userspace, then
error EOVERFLOW will be issued.

Similarly, the getdents/readdir functions now pass the full 64-bit inode
number to userspace where possible, returning EOVERFLOW instead when a
directory entry is encountered that can't be properly represented.

Note that this means that some inodes will not be stat'able on a 32-bit
system with old libraries where they were before - but it does mean that
there will be no ambiguity over what a 32-bit inode number refers to.

Note similarly that directory scans may be cut short with an error on a
32-bit system with old libraries where the scan would work before for the
same reasons.

It is judged unlikely that this situation will occur because modern glibc
uses 64-bit capable versions of stat and getdents class functions
exclusively, and that older systems are unlikely to encounter
unrepresentable inode numbers anyway.

[PATCH] BLOCK: Move the msdos device ioctl compat stuff to the msdos driver [try #6]

2006-09-30T18:52:30+00:00

Move the msdos device ioctl compat stuff from fs/compat_ioctl.c to the msdos
driver so that the msdos header file doesn't need to be included.

[PATCH] add -o flush for fat

2006-09-29T16:18:12+00:00

Fat is commonly used on removable media.  Mounting with -o flush tells the
FS to write things to disk as quickly as possible.  It is like -o sync, but
much faster (and not as safe).

[PATCH] inode-diet: Eliminate i_blksize from the inode structure

2006-09-27T15:26:18+00:00

This eliminates the i_blksize field from struct inode.  Filesystems that want
to provide a per-inode st_blksize can do so by providing their own getattr
routine instead of using the generic_fillattr() function.

Note that some filesystems were providing pretty much random (and incorrect)
values for i_blksize.

[PATCH] fat: cleanup fat_get_block(s)

get_blocks() was removed.  So, this removes it on fat, and will take
advantage of the multi block mapping.
