Since commit 5454df9c31 ("rename: check source file access early")
rename fails early for symlinks with non-existing target (regression),
because access() dereferences the link.
From access(2):
"access() checks whether the calling process can access the file pathname.
If pathname is a symbolic link, it is dereferenced."
Thus replace access() with faccessat() and lstat() as fallback,
(as in do_symlink()), that is equivalent for symlink and files.
From fsaccess(2) and stat(2):
"The faccessat() system call operates in exactly the same way as access(),
except for the differences described here.
[...]
If pathname is relative and dirfd is the special value AT_FDCWD, then pathname
is interpreted relative to the current working directory of the calling process
(like access()).
[...]
AT_SYMLINK_NOFOLLOW
If pathname is a symbolic link, do not dereference it:
instead return information about the link itself."
"lstat() is identical to stat(), except that if pathname is a symbolic link, then
it returns information about the link itself, not the file that it refers to."
Testing
-------
1) symlink with existing target
2) symlink with non-existing target
3) non-existing symlink
4) existing file
5) non-existing file
Before:
$ touch file-found
$ ln -s file-found symlink-1
$ ./rename sym symbolic- symlink-1 # XPASS.
$ echo $?
0
$ ln -s file-not-found symlink-2
$ ./rename sym symbolic- symlink-2 # FAIL! REGRESSION.
rename: symlink-2: not accessible: No such file or directory
$ echo $?
1
$ ./rename sym symbolic- symlink-3 # XFAIL.
rename: symlink-3: not accessible: No such file or directory
$ echo $?
1
$ touch file-found
$ ./rename found existing file-found # XPASS.
$ echo $?
0
$ ./rename found existing file-not-found # XFAIL.
rename: file-not-found: not accessible: No such file or directory
$ echo $?
1
After:
$ touch file-found
$ ln -s file-found symlink-1
$ ./rename sym symbolic- symlink-1 # XPASS.
$ echo $?
0
$ ln -s file-not-found symlink-2
$ ./rename sym symbolic- symlink-2 # PASS! REGRESSION FIXED.
$ echo $?
0
$ ./rename sym symbolic- symlink-3 # XFAIL.
rename: symlink-3: not accessible: No such file or directory
$ echo $?
1
$ touch file-found
$ ./rename found existing file-found # XPASS.
$ echo $?
0
$ ./rename found existing file-not-found # XFAIL.
rename: file-not-found: not accessible: No such file or directory
$ echo $?
1
And to test/simulate faccessat()'s EINVAL for AT_SYMLINK_NOFOLLOW
for Mac OS X, per commit 826538bf64 ("rename: skip faccessat()
failure if AT_SYMLINK_NOFOLLOW is not a valid flag"), forced 'if'
to evaluate to false so that lstat() is taken.
It still fails early; the error messages are slightly different
('not accessible' vs. 'stat of ... failed') but still tell same
'No such file or directory'; exit code is the same as well.
$ ./rename sym symbolic- symlink-3 # XFAIL. DIFF MSG/SAME RC.
rename: stat of symlink-3 failed: No such file or directory
$ echo $?
1
$ ./rename found existing file-not-found # XFAIL. DIFF MSG/SAME RC.
rename: stat of file-not-found failed: No such file or directory

In several pages, there is a consistent wording problem: "another"
where "other" should be used. This wording problem can be
surprisingly confusing for native speakers, especially those
unaware that in some other languages, "another" and "other" can be
expressed with the same word.

Earlier, I patched various pages to consistently use EXAMPLE as a
section heading, rather than EXAMPLES. (At that time, both headings
occurred in util-linux, with roughly equal frequency.)
Since then, I've observed that EXAMPLES is the more common usage
across a large corpus of manual pages. So, in Linux the man-pages
project, I switched to using EXAMPLES also. This patch makes the same
change for util-linux.

There is value in ensuring that manual page sections use consistently

RETURN CODES (1), or RETURN VALUE (4 instances in pages that document

Let's standardize on the EXIT STATUS (which is also what is

Using double quotes in .SH lines containing multiple words is unneeded,
and in any case is not consistently done in the util-linux manual pages,
where double quotes are used in only around half of the cases.
(This usage was long ago elminated in the man-pages project, with
no ill effects reported to date.)
Remove these quotes, so that .SH lines are more uniform, in preparation
for some (more easily) scripted doiscovery of consistency problems in
(and possibly global fixes to) the manual pages.
Other than stripping the double quotes, this patch makes no changes to
the content of the manual pages.

Lsblk throws the following error for nvmeNcXnY devices.
lsblk: nvme1c1n1: unknown device name
This is because nvmeNcXnY devices are hidden and do not have
the file /sys/block/<nvmeNcXnY>/dev.
Following patch was added
https://git.kernel.org/pub/scm/utils/util-linux/util-linux.git/commit/?id=d51f05bfecb299a830897106460bf395be440c0a
Which made lsblk read from /sys/block/<nvmeNcXnY>/device/dev
which do exist for nvmeNcXnY devices.
After the above patch, the unknown error goes away.
However, another error is encountered in the very next step.
nvme1c1n1: failed to initialize sysfs handler
This is because lsblk looks for /sys/dev/block/242:1
(nvmeNcXnY major:minor) pathname which usually exists for other
block devices but not for the nvmeNcXnY devices as they are hidden.
Below patch does not even print this error for hidden devices
and exits silently.

The commit 39f5af2598 introduces
O_NONBLOCK to avoid the tray close on open(). The side effect is that
open() is successful when there is no medium.
This is usually no problem for standard tools because the next read()
will fail. Unfortunately, libblkid ignores I/O errors for (and only
for) CDROMs to support some crazy hybrid data+audio disks. The final
result is many I/O errors in system log when O_NONBLOCK is enabled.
This patch add CDROM_DRIVE_STATUS to stop probing when there is no
disk or when the tray is open.
