Artem Bityutskiy c43be1085f UBIFS: do not use inc_link when i_nlink is zero
This patch changes the 'i_nlink' counter handling in 'ubifs_unlink()',
'ubifs_rmdir()' and 'ubifs_rename()'. In these function  'i_nlink' may become 0,
and if 'ubifs_jnl_update()' failed, we would use 'inc_nlink()' to restore
the previous 'i_nlink' value, which is incorrect from the VFS point of view and
would cause a 'WARN_ON()' (see 'inc_nlink() implementation).

This patches saves the previous 'i_nlink' value in a local variable and uses it
at the error path instead of calling 'inc_nlink()'. We do this only for the
inodes where 'i_nlink' may potentially become zero.

This change has been requested by Al Viro <viro@ZenIV.linux.org.uk>.

Artem Bityutskiy 2b1844a8c9 UBIFS: introduce helper functions for debugging checks and tests
This patch introduces helper functions for all debugging checks, so instead of
doing

if (!(ubifs_chk_flags & UBIFS_CHK_GEN))

we now do

if (!dbg_is_chk_gen(c))

This is a preparation to further changes where the flags will go away, and
we'll need to only change the helper functions, but the code which utilizes
them won't be touched.

At the same time this patch removes 'dbg_force_in_the_gaps()',
'dbg_force_in_the_gaps_enabled()', and dbg_failure_mode helpers for
consistency.

Artem Bityutskiy b137545c44 UBIFS: introduce a separate structure for budgeting info
This patch separates out all the budgeting-related information
from 'struct ubifs_info' to 'struct ubifs_budg_info'. This way the
code looks a bit cleaner. However, the main driver for this is
that we want to save budgeting information and print it later,
so a separate data structure for this is helpful.

This patch is a preparation for the further debugging output
improvements.

Hunter Adrian 8b3884a841 UBIFS: return error if link and unlink race
Consider a scenario when 'vfs_link(dirA/fileA)' and
'vfs_unlink(dirA/fileA, dirB/fileB)' race. 'vfs_link()' does not
lock 'dirA->i_mutex', so this is possible. Both of the functions
lock 'fileA->i_mutex' though. Suppose 'vfs_unlink()' wins, and takes
'fileA->i_mutex' mutex first. Suppose 'fileA->i_nlink' is 1. In this
case 'ubifs_unlink()' will drop the last reference, and put 'inodeA'
to the list of orphans. After this, 'vfs_link()' will link
'dirB/fileB' to 'inodeA'. Thir is a problem because, for example,
the subsequent 'vfs_unlink(dirB/fileB)' will add the same inode
to the list of orphans.

This problem was reported by J. R. Okajima <hooanon05@yahoo.co.jp>

Wrap access to task credentials so that they can be separated more easily from

Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id().

Change some task->e?[ug]id to task_e?[ug]id().  In some places it makes more
sense to use RCU directly rather than a convenient wrapper; these will be
addressed by later patches.

Always allow truncations to zero, even if budgeting thinks there

Otherwise, the following happans:

2. truncate the file, which fails with ENOSPC, which is not good.
