Running generic/475(filesystem consistent tests after power cut) could
easily trigger unattached inode error while doing fsck:
Unattached zero-length inode 39405. Clear? no
Unattached inode 39405
Connect to /lost+found? no
Above inconsistence is caused by following process:
P1 P2
ext4_create
inode = ext4_new_inode_start_handle // itable records nlink=1
ext4_add_nondir
err = ext4_add_entry // ENOSPC
ext4_append
ext4_bread
ext4_getblk
ext4_map_blocks // returns ENOSPC
drop_nlink(inode) // won't be updated into disk inode
ext4_orphan_add(handle, inode)
ext4_orphan_file_add
ext4_journal_stop(handle)
jbd2_journal_commit_transaction // commit success
>> power cut <<
ext4_fill_super
ext4_load_and_init_journal // itable records nlink=1
ext4_orphan_cleanup
ext4_process_orphan
if (inode->i_nlink) // true, inode won't be deleted
Then, allocated inode will be reserved on disk and corresponds to no
dentries, so e2fsck reports 'unattached inode' problem.
The problem won't happen if orphan file feature is disabled, because
ext4_orphan_add() will update disk inode in orphan list mode. There
are several places not updating disk inode while putting inode into
orphan area, such as ext4_add_nondir(), ext4_symlink() and whiteout
in ext4_rename(). Fix it by updating inode into disk in all error
branches of these places.

We got a filesystem inconsistency issue below while running generic/475
I/O failure pressure test with fast_commit feature enabled.
Symlink /p3/d3/d1c/d6c/dd6/dce/l101 (inode #132605) is invalid.
If fast_commit feature is enabled, a special fast_commit journal area is
appended to the end of the normal journal area. The journal->j_last
point to the first unused block behind the normal journal area instead
of the whole log area, and the journal->j_fc_last point to the first
unused block behind the fast_commit journal area. While doing journal
recovery, do_one_pass(PASS_SCAN) should first scan the normal journal
area and turn around to the first block once it meet journal->j_last,
but the wrap() macro misuse the journal->j_fc_last, so the recovering
could not read the next magic block (commit block perhaps) and would end
early mistakenly and missing tN and every transaction after it in the
following example. Finally, it could lead to filesystem inconsistency.
| normal journal area | fast commit area |
+-------------------------------------------------+------------------+
| tN(rere) | tN+1 |~| tN-x |...| tN-1 | tN(front) | .... |
+-------------------------------------------------+------------------+
/ / /
start journal->j_last journal->j_fc_last
This patch fix it by use the correct ending journal->j_last.

It's been a long time since anyone has looked at what struct tty_struct
looks like in memory, turns out there was a ton of holes.
So move things around a bit, change one variable (closing) from being an
int to a bool (it is only being tested for 0/1), and we end up saving 40
bytes per structure overall on x86-64 systems.
Before this patch:

/* sum members: 665, holes: 8, sum holes: 31 */
/* forced alignments: 2, forced holes: 1, sum forced holes: 4 */

Some count types are already 'size_t' for a long time. Some were
switched to 'size_t' recently. Unify the rest with those now.
This allows for some min_t()s to become min()s. And make one min()
an explicit min_t() as we are comparing signed 'room' to unsigned
'count'.

The jiffies tests in n_tty_receive_overrun() are simplified ratelimiting
(without locking). We could use struct ratelimit_state and the helpers,
but to me, it occurs to be too complex for this use case.
But the code currently tests both if the time passed (the first
time_after()) and if jiffies wrapped around (the second time_after()).
time_is_before_jiffies() takes care of both, provided overrun_time is
initialized at the allocation time.
So switch to time_is_before_jiffies(), the same what ratelimiting does.

====================
Introduce IEP driver and packet timestamping support
This series introduces Industrial Ethernet Peripheral (IEP) driver to
support timestamping of ethernet packets and thus support PTP and PPS
for PRU ICSSG ethernet ports.
This series also adds 10M full duplex support for ICSSG ethernet driver.
There are two IEP instances. IEP0 is used for packet timestamping while IEP1
is used for 10M full duplex support.
This is v7 of the series [v1]. It addresses comments made on [v6].
This series is based on linux-next(#next-20230823).
Changes from v6 to v7:
*) Dropped blank line in example section of patch 1.
*) Patch 1 previously had three examples, removed two examples and kept only
one example as asked by Krzysztof.
*) Added Jacob Keller's RB tag in patch 5.
*) Dropped Roger's RB tags from the patches that he has authored (Patch 3 and 4)
Changes from v5 to v6:
*) Added description of IEP in commit messages of patch 2 as asked by Rob.
*) Described the items constraints properly for iep property in patch 2 as
asked by Rob.
*) Added Roger and Simon's RB tags.
Changes from v4 to v5:
*) Added comments on why we are using readl / writel instead of regmap_read()
/ write() in icss_iep_gettime() / settime() APIs as asked by Roger.
*) Added Conor's RB tag in patch 1 and 2.
Change from v3 to v4:
*) Changed compatible in iep dt bindings. Now each SoC has their own compatible
in the binding with "ti,am654-icss-iep" as a fallback as asked by Conor.
*) Addressed Andew's comments and removed helper APIs icss_iep_readl() /
writel(). Now the settime/gettime APIs directly use readl() / writel().
*) Moved selecting TI_ICSS_IEP in Kconfig from patch 3 to patch 4.
*) Removed forward declaration of icss_iep_of_match in patch 3.
*) Replaced use of of_device_get_match_data() to device_get_match_data() in
patch 3.
*) Removed of_match_ptr() from patch 3 as it is not needed.
Changes from v2 to v3:
*) Addressed Roger's comment and moved IEP1 related changes in patch 5.
*) Addressed Roger's comment and moved icss_iep.c / .h changes from patch 4
to patch 3.
*) Added support for multiple timestamping in patch 4 as asked by Roger.
*) Addressed Andrew's comment and added comment in case SPEED_10 in
icssg_config_ipg() API.
*) Kept compatible as "ti,am654-icss-iep" for all TI K3 SoCs
Changes from v1 to v2:
*) Addressed Simon's comment to fix reverse xmas tree declaration. Some APIs
in patch 3 and 4 were not following reverse xmas tree variable declaration.
Fixed it in this version.
*) Addressed Conor's comments and removed unsupported SoCs from compatible
comment in patch 1.
*) Addded patch 2 which was not part of v1. Patch 2, adds IEP node to dt
bindings for ICSSG.

For AM65x SR2.0 it's required to enable IEP1 in raw 64bit mode which is
used by PRU FW to monitor the link and apply w/a for 10M link issue.
Note. No public errata available yet.
Without this w/a the PRU FW will stuck if link state changes under TX
traffic pressure.
Hence, add support for 10M full duplex for AM65x SR2.0:
- add new IEP API to enable IEP, but without PTP support
- add pdata quirk_10m_link_issue to enable 10M link issue w/a.

Add packet timestamping TS and PTP PHC clock support.
For AM65x and AM64x:
- IEP1 is not used
- IEP0 is configured in shadow mode with 1ms cycle and shared between
Linux and FW. It provides time and TS in number cycles, so special
conversation in ns is required.
- IEP0 shared between PRUeth ports.
- IEP0 supports PPS, periodic output.
- IEP0 settime() and enabling PPS required FW interraction.
- RX TS provided with each packet in CPPI5 descriptor.
- TX TS returned through separate ICSSG hw queues for each port. TX TS
readiness is signaled by INTC IRQ. Only one packet at time can be requested
for TX TS.

Use `memcpy` since `console_buf` is not expected to be NUL-terminated
and it more accurately describes what is happening with the buffers
`console_buf` and `string` as per Kees' analysis [1].
Also mark char buffer as `__nonstring` as per Kees' suggestion [2].
This change now makes it more clear what this code does and that
`console_buf` is not expected to be NUL-terminated.
