Subject: [PATCH] vmstat: Support for timestamps with '-t' & fix for '-wd'
|
||||
|
||||
From now the vmstat can append a timestamp to each line in the
|
||||
VMSTAT and DISKSTAT mode. You can achieve that with the '-t'
|
||||
switch.
|
||||
The '-w' switch now works in the DISKSTAT mode too.

Subject: [PATCH] watch: Don't leak extra fds to the child
|
||||
|
||||
Once the write side of the pipe has been duped to stdout for the child,
|
||||
the original pipefd is no longer needed, so it can be closed to avoid
|
||||
leaking to the child.
|
||||
|
||||
The leak can easily be seen with "watch ls -l /proc/self/fd", but I
|
||||
found this due to "watch lvs" diagnosing itself:
|
||||
|
||||
File descriptor 4 (pipe:[3163616]) leaked on lvs invocation.

||||
