Bug #15020 "Can't find files" message incorrect for error 24

Description:
Looking http://bugs.mysql.com/15019 you will see the following errors:

051116 16:19:38 [ERROR] /home/ndbdev/jmiller/builds/libexec/mysqld: Can't find
file: '.
/cluster_replication/binlog_index.frm' (errno: 24)

errno: 24 is actually:
OS error code  24:  Too many open files

So the message is not correct in stating that it can't find the file, it just can not open
the file.

How to repeat:
See http://bugs.mysql.com/15019

Suggested fix:
Change message:
051116 16:19:38 [ERROR] /home/ndbdev/jmiller/builds/libexec/mysqld: Can not open file:
'./cluster_replication/binlog_index.frm' (errno: 24)

Error message will now say "Could not open file (errno: 24)"
Pushed to 5.0.19 and 5.1.6
[24 Jan 2006 12:45] Magnus Svensson 
Not pushed to 5.1 yet. Only to 5.0.19
[26 Jan 2006 3:10] Mike Hillyer 
When you say not pushed in 5.1 yet do you imply that it will be pushed in the near future?
If I add a changelog entry I also need to close the bugreport, which would be the wrong
course of action if this bug is also to be fixed in 5.1. Changing status to Need Doc Info.
