[In commit 9ed437c50d89eabae763dd422579f73fdebf288d we fixed a problem with standard permissions on newly-created inodes, when POSIX ACLs are enabled. This cleans it up...]
The attached patch separate jffs2_init_acl() into two parts.
The one is jffs2_init_acl_pre() called from jffs2_new_inode(). It compute ACL oriented inode->i_mode bits, and allocate in-memory ACL objects associated with the new inode just before when inode meta infomation is written to the medium.
The other is jffs2_init_acl_post() called from jffs2_symlink(), jffs2_mkdir(), jffs2_mknod() and jffs2_do_create(). It actually writes in-memory ACL objects into the medium next to the success of writing meta-information.
In the current implementation, we have to write a same inode meta infomation twice when inode->i_mode is updated by the default ACL. However, we can avoid the behavior by putting an updated i_mode before it is written at first, as jffs2_init_acl_pre() doing.

In particular, remove the bit in the LICENCE file about contacting Red Hat for alternative arrangements. Their errant IS department broke that arrangement a long time ago -- the policy of collecting copyright assignments from contributors came to an end when the plug was pulled on the servers hosting the project, without notice or reason.
We do still dual-license it for use with eCos, with the GPL+exception licence approved by the FSF as being GPL-compatible. It's just that nobody has the right to license it differently.

[PATCH] remove many unneeded #includes of sched.h
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up.
To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble.
Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

[JFFS2] Support new device nodes
Device node major/minor numbers are just stored in the payload of a single data node. Just extend that to 4 bytes and use new_encode_dev() for it.
We only use the 4-byte format if we _need_ to, if !old_valid_dev(foo). This preserves backwards compatibility with older code as much as possible. If we do make devices with major or minor numbers above 255, and then mount the file system with the old code, it'll just read the first two bytes and get the numbers wrong. If it comes to garbage-collect it, it'll then write back those wrong numbers. But that's about the best we can expect.

[JFFS2][XATTR] XATTR support on JFFS2 (version. 5)
This attached patches provide xattr support including POSIX-ACL and SELinux support on JFFS2 (version.5).
There are some significant differences from previous version posted at last December. The biggest change is addition of EBS(Erase Block Summary) support. Currently, both kernel and usermode utility (sumtool) can recognize xattr nodes which have JFFS2_NODETYPE_XATTR/_XREF nodetype.
In addition, some bugs are fixed. - A potential race condition was fixed. - Unexpected fail when updating a xattr by same name/value pair was fixed. - A bug when removing xattr name/value pair was fixed.
The fundamental structures (such as using two new nodetypes and exclusion mechanism by rwsem) are unchanged. But most of implementation were reviewed and updated if necessary. Espacially, we had to change several internal implementations related to load_xattr_datum() to avoid a potential race condition.
