The patch titled
Subject: lseek: the "whence" argument is called "whence"
has been added to the -mm tree. Its filename is
lseek-the-whence-argument-is-called-whence.patch
Before you just go and hit "reply", please:
a) Consider who else should be cc'ed
b) Prefer to cc a suitable mailing list as well
c) Ideally: find the original patch on the mailing list and do a
reply-to-all to that, adding suitable additional cc's
*** Remember to use Documentation/SubmitChecklist when testing your code ***
The -mm tree is included into linux-next and is updated
there every 3-4 working days
------------------------------------------------------
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
Subject: lseek: the "whence" argument is called "whence"
But the kernel decided to call it "origin" instead. Fix most of the
sites.
