profile provider: is it me doing stupid things?
...e. Following DTrace snippet is tried:
dtrace -q -p 3173 -n ''syscall::read:entry { @[probefunc] = count(); } profile:::tick-250ms { printa("%6s %@6d\n", @); printf("\n"); clear(@); }''
This to chop up a one second interval into four different equal sized 250 millsec slots. Counting the number of read and write syscalls that fall in each slot.
This one is run against a process that reads a single character and writes that character (stdin, stdout) continuously. Wrote it myself so I dare say it is functionally correct :-)
The output I get is:

[PATCH 1/1] OCFS2: timer to queue scan of all orphan slots
On unlink, all nodes check for the dentry in dcache and if present they mark
the node as unlinked. The last node that purges the inode will clean it from
orphan directory. When there is a memory pressure, a dentry may not be around
and hence the inode is not marked as deleted and this will lead the file to be
in the orphan directory till the slot is re-used during next mount.
This patch initiates
