udf: Fix BUG_ON() in destroy_inode()

2008-11-27T16:38:28+00:00

udf_clear_inode() can leave behind buffers on mapping's i_private list (when
we truncated preallocation). Call invalidate_inode_buffers() so that the list
is properly cleaned-up before we return from udf_clear_inode(). This is ugly
and suggest that we should cleanup preallocation earlier than in clear_inode()
but currently there's no such call available since drop_inode() is called under
inode lock and thus is unusable for disk operations.

vfs: Use const for kernel parser table

2008-10-13T17:10:37+00:00

This is a much better version of a previous patch to make the parser
tables constant. Rather than changing the typedef, we put the "const" in
all the various places where its required, allowing the __initconst
exception for nfsroot which was the cause of the previous trouble.

This was posted for review some time ago and I believe its been in -mm
since then.

udf: add llseek method

2008-09-08T18:31:04+00:00

UDF currently doesn't set a llseek method for regular files, which
means it will fall back to default_llseek.  This means no one can seek
beyond 2 Gigabytes on udf, and that there's not protection vs
the i_size updates from writers.

udf: Fix error paths in udf_new_inode()

2008-08-19T09:05:05+00:00

I case we failed to allocate memory for inode when creating it, we did not
properly free block already allocated for this inode. Move memory allocation
before the block allocation which fixes this issue (thanks for the idea go to
Ingo Oeser ). Also remove a few superfluous
initializations already done in udf_alloc_inode().

udf: Fix lock inversion between iprune_mutex and alloc_mutex (v2)

2008-08-19T09:04:36+00:00

A memory allocation inside alloc_mutex must not recurse back into the
filesystem itself because that leads to lock inversion between iprune_mutex and
alloc_mutex (and thus to deadlocks - see traces below). alloc_mutex is actually
needed only to update allocation statistics in the superblock so we can drop it
before we start allocating memory for the inode.

SL*B: drop kmem cache argument from constructor

2008-07-26T19:00:07+00:00

Kmem cache passed to constructor is only needed for constructors that are
themselves multiplexeres.  Nobody uses this "feature", nor does anybody uses
passed kmem cache in non-trivial way, so pass only pointer to object.

Non-trivial places are:
	arch/powerpc/mm/init_64.c
	arch/powerpc/mm/hugetlbpage.c

This is flag day, yes.

udf: Fix regression in UDF anchor block detection

2008-06-24T09:38:03+00:00

In some cases it could happen that some block passed test in
udf_check_anchor_block() even though udf_read_tagged() refused to read it later
(e.g. because checksum was not correct).  This patch makes
udf_check_anchor_block() use udf_read_tagged() so that the checking is
stricter.

This fixes the regression (certain disks unmountable) caused by commit
423cf6dc04eb79d441bfda2b127bc4b57134b41d.
