[PATCH] fts: introduce FTS_NOATIME

This gives clients the option to try a non-invasive traversal, where merely visiting a directory does not update its timestamp, where such is supported by the kernel. Note that whiteout support and O_NOATIME support are orthogonal: there is no way to get O_NOATIME behavior when using __opendir2 to

I think that would also need a change to ftw(). That's in gnulib. On Thu, Jul 7, 2011 at 2:10 PM, Eric Blake wrote: > Follow-up Comment #1, bug #33724 (project findutils): > > POSIX requires this behavior.  However, Linux provides the O_NOATIME flag to > open() to work around this behavior - so

fts and O_NOATIME

http://savannah.gnu.org/bugs/?33724 raised the issue that findutils is updating directory atime as part of traversing a hierarchy (and, according to POSIX, this behavior is the correct default). However, it would be nice to support the use of fts in a mode where O_NOATIME is used, so that director

[bug #33724] Find command is changing the access time of directory

Follow-up Comment #1, bug #33724 (project findutils): POSIX requires this behavior. However, Linux provides the O_NOATIME flag to open() to work around this behavior - so the obvious conclusion is that find should support the option of requesting the use of the O_NOATIME flag. It can't be on by
