reiserfs: unpack tails on quota files

2008-04-28T15:58:46+00:00

Quota files cannot have tails because quota_write and quota_read functions do
not support them.  So far when quota files did have tail, we just refused to
turn quotas on it.  Sadly this check has been wrong and so there are now
plenty installations where quota files don't have NOTAIL flag set and so now
after fixing the check, they suddently fail to turn quotas on.  Since it's
easy to unpack the tail from kernel, do this from reiserfs_quota_on() which
solves the problem and is generally nicer to users anyway.

use __u32 in linux/reiserfs_fs.h

2008-02-08T17:22:41+00:00

Since this header is exported to userspace and all the other types in the
header have been scrubbed, this brings the last straggler in line.

Use helpers to obtain task pid in printks

2007-10-19T18:53:43+00:00

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.

The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.

reiserfs: ignore on disk s_bmap_nr value

2007-10-19T18:53:35+00:00

Implement support for file systems larger than 8 TiB.

The reiserfs superblock contains a 16 bit value for counting the number of
bitmap blocks.  The rest of the disk format supports file systems up to 2^32
blocks, but the bitmap block limitation artificially limits this to 8 TiB with
a 4KiB block size.

Rather than trust the superblock's 16-bit bitmap block count, we calculate it
dynamically based on the number of blocks in the file system.  When an
incorrect value is observed in the superblock, it is zeroed out, ensuring that
older kernels will not be able to mount the file system.

Userspace support has already been implemented and shipped in reiserfsprogs
3.6.20.

reiserfs: fix usage of signed ints for block numbers

2007-10-19T18:53:35+00:00

Do a quick signedness check for block numbers.  There are a number of places
where signed integers are used for block numbers, which limits the usable file
system size to 8 TiB.  The disk format, excepting a problem which will be
fixed in the following patch, supports file systems up to 16 TiB in size.
This patch cleans up those sites so that we can enable the full usable size.

fix preprocessor idiocy in reiserfs

2007-07-29T02:42:22+00:00

	#x blocks expansion of macro argument, but it won't do you any
good if it's already been expanded...  As it is, RFALSE(cond, ....)
ended up with stringified _expanded_ cond.  Real fun when cond contains
something like le32_to_cpu() and you are on a big-endian box...

[PATCH] mark struct inode_operations const 3

2007-02-12T17:48:46+00:00

Many struct inode_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.
