/proc/tty/ldisc appear to be unused as a directory and
it had been always that way.
But it is userspace visible thing.
Cowardly remove only in-kernel variable holding it.

Currently lookup for /proc/$PID first goes through spinlock and whole list
of misc /proc entries only to confirm that, yes, /proc/42 can not possibly
match random proc entry.
List is is several dozens entries long (52 entries on my setup).
None of this is necessary.
Try to convert dentry name to integer first.
If it works, it must be /proc/$PID.
If it doesn't, it must be random proc entry.
Based on patch from Al Viro.

* remove proc_create(NULL, ...) check, let it oops
* warn about proc_create("", ...) and proc_create("very very long name", ...)
proc code keeps length as u8, no 256+ name length possible
* warn about proc_create("123", ...)
/proc/$PID and /proc/misc namespaces are separate things,
but dumb module might create funky a-la $PID entry.
* remove post mortem strchr('/') check
Triggering it implies either strchr() is buggy or memory corruption.
It should be VFS check anyway.
In reality, none of these checks will ever trigger,
it is preparation for the next patch.
Based on patch from Al Viro.

proc_uid_seq_operations, proc_gid_seq_operations and
proc_projid_seq_operations are only called in proc_id_map_open with
seq_open as const struct seq_operations so we can constify the 3
structures and update proc_id_map_open prototype.

This patch integrates creation of sysfs groups and
attributes into NILFS file system driver.
It was found the issue with nilfs_sysfs_{create/delete}_snapshot_group
functions by Michael L Semon <[email protected]> in the first
version of the patch:

The reason of the issue was placement of

nilfs->ns_cptree_lock protection. But this protection is unnecessary and
wrong solution. The second version of the patch fixes this issue.

This patchset implements creation of sysfs groups and attributes with
the purpose to show NILFS2 volume details, internal state of the driver
and to manage internal state of NILFS2 driver.
Sysfs is a virtual file system that exports information about devices
and drivers from the kernel device model to user space, and is also used
for configuration. NILFS2 is a complex file system that has segctor
thread, GC thread, checkpoint/snapshot model and so on. Sysfs namespace
provides native and easy way for: (1) getting info and statistics about
volume state; (2) getting info and configuration of internal subsystems
(segctor thread); (3) snapshots management.
Suggested patchset provides basis for managing segctor thread behaviour
and manipulation by snapshots. Currently, it informs only about segctor
thread's internal parameters and about mounted snapshots. But sysfs
interface can provide easy and simple way for deep management of segctor
thread and snapshots.
This patchset provides opportunity to manage interval of periodical
update of superblock (in seconds). Default value is 10 seconds. Now a
user can increase this value by means of
nilfs2/<device>/superblock/sb_update_frequency attribute in the case of
necessity.
Also the patchset provides opportunity to get information easily about
key volumes's parameters (free blocks, superblock write count,
superblock update frequency, latest segment info, dirty data blocks
count, count of clean segments, count of dirty segments and so on) in
real time manner. Such information can be used in scripts for subtle
management of filesystem.
Implemented functionality creates such groups:
(1) /sys/fs/nilfs2 - root group
(2) /sys/fs/nilfs2/features - group contains attributes that describe NILFS
file system driver features
(3) /sys/fs/nilfs2/<device> - group contains attributes that describe file
system partition's details
(4) /sys/fs/nilfs2/<device>/superblock - group contains attributes that describe
superblock's details
(5) /sys/fs/nilfs2/<device>/segctor - group contains attributes that describe
segctor thread activity details
(6) /sys/fs/nilfs2/<device>/segments - group contains attributes that describe
details about volume's segments
(7) /sys/fs/nilfs2/<device>/checkpoints - group contains attributes that describe
details about volume's checkpoints
(8) /sys/fs/nilfs2/<device>/mounted_snapshots - group contains group for every
mounted snapshot
(9) /sys/fs/nilfs2/<device>/mounted_snapshots/<snapshot> - group contains
details about mounted snapshot
This patch (of 9):
This patch adds code of creation /sys/fs/nilfs2 group and
/sys/fs/nilfs2/features group.
The features group contains attributes that describe NILFS
file system driver features:
(1) revision - show current revision of NILFS file system driver.
There are two formats of timestamp output - seconds and human-readable
format. Every showed timestamp has two sysfs files (time-<xxx> and
time-<xxx>-secs). One sysfs file (time-<xxx>) shows time in
human-readable format. Another sysfs file (time-<xxx>-secs) shows time in
seconds.
It was reported by Michael Semon that timestamp output in human-readable
format should be changed from "2014-4-12 14:5:38" to "2014-04-12
14:05:38". Second version of the patch fixes this issue.

befs_dump_super_block was called between befs_load_sb and befs_check_sb.
It has been reported to crash (5/900) with null block testing.
This patch loads, checks and only dump superblock if it's a valid one
then brelse bh.
(befs_dump_super_block uses disk_sb (bh->b_data) so it seems we need to
call it before brelse(bh) but I don't know why befs_check_sb was called
after brelse. Another thing I don't understand is why this problem
appears now).

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.

The interrupt handler gets the driver data associated with the RTC
device and doesn't check it for validity. This can cause a NULL pointer
being dereferenced when and interrupt fires before the driver data was
properly set up.
Fix this by setting the driver data earlier (before the interrupt is
requested).

In particular seeing zero in eft->month is problematic, as it results in
-1 (converted to unsigned int, i.e. yielding 0xffffffff) getting passed
to rtc_year_days(), where the value gets used as an array index
(normally resulting in a crash). This was observed with the driver
enabled on x86 on some Fujitsu system (with possibly not up to date
firmware, but anyway).
Perhaps efi_read_alarm() should not fail if neither enabled nor pending
are set, but the returned time is invalid?

of_match_ptr() helper"
Commit 5516f0971793 ("drivers/rtc/rtc-ds1742.c: remove redundant
of_match_ptr() helper") has description as: "'ds1742_rtc_of_match' is
always compiled in. Hence the helper macro is not needed".
It is not true, of_match_ptr() macro makes of_device_id parameter unused
and this constant is declared with __maybe_unused attribute, so normally
this variable should be discarded by linker. This patch revers this
commit, since there are no reason to compile of_device_id constant for
non-DT systems.

If the expiring_list is empty, we can avoid a costly spinlock in the
rcu-walk path through autofs4_d_manage (once the rest of the path
becomes rcu-walk friendly).

The variable 'ino' already exists and already has the correct value.
The d_fsdata of a dentry is never changed after the d_fsdata is
instantiated, so this new assignment cannot be necessary.
It was introduced in commit b5b801779d59 ("autofs4: Add d_manage()
dentry operation").
