hfsplus: use raw bio access for the volume headers

2010-11-23T13:37:47+00:00

The hfsplus backup volume header is located two blocks from the end of
the device.  In case of device sizes that are not 4k aligned this means
we can't access it using buffer_heads when using the default 4k block
size.

Switch to using raw bios to read/write all buffer headers.  We were not
relying on any caching behaviour of the buffer heads anyway.  Additionally
always read in the backup volume header during mount to verify that we
can actually read it.

hfsplus: use atomic bitops for the superblock flags

2010-10-01T03:45:20+00:00

The flags in the HFS+-specific superlock do get modified during runtime,
use atomic bitops to make the modifications SMP safe.

hfsplus: fix HFSPLUS_SB calling convention

2010-10-01T03:42:59+00:00

HFSPLUS_SB doesn't return a pointer to the hfsplus-specific superblock
information like all other FOO_SB macros, but dereference the pointer in a way
that made it look like a direct struct derefence.  This only works as long
as the HFSPLUS_SB macro is used directly and prevents us from keepig a local
hfsplus_sb_info pointer.  Fix the calling convention and introduce a local
sbi variable in all functions that use it constantly.

hfsplus: refuse to mount volumes larger than 2TB

2009-10-29T14:39:27+00:00

As found in , hfsplus is using type u32
rather than sector_t for some sector number calculations.

In particular, hfsplus_get_block() does:

        u32 ablock, dblock, mask;
...
        map_bh(bh_result, sb, (dblock << HFSPLUS_SB(sb).fs_shift) + HFSPLUS_SB(sb).blockoffset + (iblock & mask));

I am not confident that I can find and fix all cases where a sector number
may be truncated.  For now, avoid data loss by refusing to mount HFS+
volumes with more than 2^32 sectors (2TB).

[PATCH] hfs: cleanup HFS+ prints

2006-01-19T03:20:22+00:00

Add the log level and a "hfs: " prefix to all kernel prints.  (HFS and HFS+
will use the same prefix, as they share some code and could be merged at some
point.)

[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
