[PATCH] uml: hostfs - fix possible PAGE_CACHE_SHIFT overflows

2005-12-29T17:48:15+00:00

Prevent page->index << PAGE_CACHE_SHIFT from overflowing.

There is a casting there, but was added without care, so it's at the wrong
place. Note the extra parens around the shift - "+" is higher precedence than
"<<", leading to a GCC warning which saved all us.

[PATCH] Hostfs: remove unused var

2005-12-29T17:48:15+00:00

Trivial removal of unused variable from this file - doesn't even change the
generated assembly code, in fact (gcc should trigger a warning for unused value
here).

[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reason

2005-11-09T15:55:57+00:00

This patch removes almost all inclusions of linux/version.h.  The 3
#defines are unused in most of the touched files.

A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is
unfortunatly in linux/version.h.

There are also lots of #ifdef for long obsolete kernels, this was not
touched.  In a few places, the linux/version.h include was move to where
the LINUX_VERSION_CODE was used.

quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'`

search pattern:
/UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h

This is the fs/ part of the big kfree cleanup patch.

Remove pointless checks for NULL prior to calling kfree() in fs/.

[PATCH] uml: remove empty hostfs_truncate method

2005-09-30T19:41:18+00:00

Calling truncate() on hostfs spits a kernel warning "Something isn't
implemented here", but it still works fine.

Indeed, hostfs i_op->truncate doesn't do anything.  But hostfs_setattr() ->
set_attr() correctly detects ATTR_SIZE and calls truncate() on the host.  So
we should be safe (using ftruncate() may be better, in case the file is
unlinked on the host, but we aren't sure to have the file open for writing,
and reopening it would cause the same races; plus nobody should expect UML to
be so careful).

So, the warning is wrong, because the current implementation is working.  Al,
am I correct, and can the warning be therefore dropped?

[PATCH] update filesystems for new delete_inode behavior

2005-09-09T20:57:27+00:00

Update the file systems in fs/ implementing a delete_inode() callback to
call truncate_inode_pages().  One implementation note: In developing this
patch I put the calls to truncate_inode_pages() at the very top of those
filesystems delete_inode() callbacks in order to retain the previous
behavior.  I'm guessing that some of those could probably be optimized.

[PATCH] uml: hostfs: unuse ROOT_DEV

2005-07-14T16:00:25+00:00

Minimal patch removing uses of ROOT_DEV; next patch unexports it.  I've
opposed this, but I've planned to reintroduce the functionality without using
ROOT_DEV.

Remove old useless header that was used in Ye Olde Times during 2.4->2.5
porting to abstract differences.  It's definitions are no more used anyway, so
let's finally kill it.
