ext2: Explicitly assign values to on-disk enum of filetypes

2009-12-10T14:02:51+00:00

It is somewhat dangerous to use a straight enum here, because this will
reassign values of later variables if one of the earlier ones is removed.

ext2: tighten restrictions on inode flags

2009-01-08T16:31:00+00:00

At the moment there are few restrictions on which flags may be set on
which inodes.  Specifically DIRSYNC may only be set on directories and
IMMUTABLE and APPEND may not be set on links.  Tighten that to disallow
TOPDIR being set on non-directories and only NODUMP and NOATIME to be set
on non-regular file, non-directories.

Introduces a flags masking function which masks flags based on mode and
use it during inode creation and when flags are set via the ioctl to
facilitate future consistency.

ext2: don't inherit inappropriate inode flags from parent

2009-01-08T16:31:00+00:00

At present BTREE/INDEX is the only flag that new ext2 inodes do NOT
inherit from their parent.  In addition prevent the flags DIRTY, ECOMPR,
INDEX, IMAGIC and TOPDIR from being inherited.  List inheritable flags
explicitly to prevent future flags from accidentally being inherited.

This fixes the TOPDIR flag inheritance bug reported at
http://bugzilla.kernel.org/show_bug.cgi?id=9866.

ext2: fix typo in Hurd part of include/linux/ext2_fs.h

2008-07-25T17:53:31+00:00

Fix typo in Hurd part of include/linux/ext2_fs.h

The ';' here is redundant or can even pose problem.  This is actually not
used by the Linux kernel, but it is exposed in GNU/Hurd.

fix up ext2_fs.h for userspace after reservations backport

2007-11-29T17:24:53+00:00

In commit a686cd898bd999fd026a51e90fb0a3410d258ddb:

 "Val's cross-port of the ext3 reservations code into ext2."

include/linux/ext2_fs.h got a new function whose return value is only
defined if __KERNEL__ is defined. Putting #ifdef __KERNEL__ around the
function seems to help, patch below.

ext2: avoid rec_len overflow with 64KB block size

2007-10-22T15:13:18+00:00

With 64KB blocksize, a directory entry can have size 64KB which does not
fit into 16 bits we have for entry length.  So we store 0xffff instead and
convert the value when read from / written to disk.

[PATCH] BLOCK: Move common FS-specific ioctls to linux/fs.h [try #6]

2006-09-30T18:52:28+00:00

Move common FS-specific ioctls from linux/ext2_fs.h to linux/fs.h as FS_IOC_*
and FS_IOC32_* and have the users of them use those as a base.

Also move the GETFLAGS/SETFLAGS flags to linux/fs.h as FS_*_FL macros, and then
have the other users use them as a base.
