More clearly explain the notion of locked mounts
|
|
|
|
For a long time, this manual page has had a brief discussion of
|
|
|
|
"locked" mounts, without clearly saying what this concept is, or
|
|
|
|
why it exists. Expand the discussion with an explanation of what
|
|
|
|
locked mounts are, why mounts are locked, and some examples of the
|
|
|
|
effect of locking.

|
Fix EBADF error description
|
|
|
|
Make the description of the EBADF error for invalid 'dirfd' more
|
|
|
|
uniform. In particular, note that the error only occurs when the
|
|
|
|
pathname is relative, and that it occurs when the 'dirfd' is
|
|
|
|
neither valid *nor* has the value AT_FDCWD.
|
|
|
|
|
|
|
|
Various pages
|
|
|
|
Michael Kerrisk
|
|
|
|
ERRORS: combine errors into a single alphabetic list
|
|
|
|
These pages split out extra errors for some APIs into a separate
|
|
|
|
list. Probably, the pages are easier to ready if all errors are
|
|
|
|
combined into a single list.
|
|
|
|
|
|
|
|
Note that there still remain a few pages where the errors are
|
|
|
|
listed separately for different APIs. For the moment, it seems
|
|
|
|
best to leave those pages as is, since the error lists are
|
|
|
|
largely distinct in those pages.

|
|
|
|
Many times, these pages use the terminology "mount point", where
|
|
|
|
"mount" would be better. A "mount point" is the location at which
|
|
|

a mount is attached. A "mount" is an association between a

ERRORS: combine errors into a single list
|
|
|
|
These pages split out errors into separate lists (perhaps per API,
|
|
|
|
perhaps "may" vs "shall", perhaps "Linux-specific" vs
|
|
|
|
standard(??)), but there's no good reason to do this. It makes
|
|
|
|
the error list harder to read, and is inconsistent with other
|
|
|
|
pages. So, combine the errors into a single list.
