fs: Replace CURRENT_TIME_SEC with current_time() for inode timestamps

2016-09-28T01:06:22+00:00

CURRENT_TIME_SEC is not y2038 safe. current_time() will
be transitioned to use 64 bit time along with vfs in a
separate patch.
There is no plan to transistion CURRENT_TIME_SEC to use
y2038 safe time interfaces.

current_time() will also be extended to use superblock
range checking parameters when range checking is introduced.

This works because alloc_super() fills in the the s_time_gran
in super block to NSEC_PER_SEC.

minix zmap block counts calculation fix

2014-08-08T22:57:20+00:00

The original minix zmap blocks calculation was correct, in the formula of:

	sbi->s_nzones - sbi->s_firstdatazone + 1

It is

	sp->s_zones - (sp->s_firstdatazone - 1)

in the minix3 source code.

But a later commit 016e8d44bc06 ("fs/minix: Verify bitmap block counts
before mounting") has changed it unfortunately as:

  sbi->s_nzones - (sbi->s_firstdatazone + 1)

This would show free blocks one block less than the real when the total
data blocks are in "full zmap blocks plus one".

This patch corrects that zmap blocks calculation and tidy a printk
message while at it.

fs/minix: Verify bitmap block counts before mounting

2011-11-19T16:13:26+00:00

Newer versions of MINIX can create filesystems that allocate an extra
bitmap block.  Mounting of this succeeds, but doing a statfs call will
result in an oops in count_free because of a negative number being used
for the bh index.

Avoid this by verifying the number of allocated blocks at mount time,
erroring out if there are not enough and make statfs ignore the extras
if there are too many.

switch minix to ->evict_inode(), fix write_inode/delete_inode race

2010-08-09T20:47:53+00:00

We need to wait for completion of possible writeback in progress
before we clear on-disk inode during deletion.

CRED: Wrap task credential accesses in the Minix filesystem

2008-11-13T23:38:57+00:00

Wrap access to task credentials so that they can be separated more easily from
the task_struct during the introduction of COW creds.

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.
