For operations that create vnodes on the server such as CreateFile, MakeDir or Symlink, the server will store its own current time as the mtime if the client doesn't pass in a time in the accompanying StoreStatus structure. If the server and client clocks are not well synchronized, the client may see timestamps in the future or inconsistent dependency checks with "make" for files that are not modified after creation: make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has modification time 0.14 s in the future make[2]: warning: Clock skew detected. Your build may be incomplete. This is already handled correctly for non yfs operations; also set the mtime for the corresponding yfs operations. Changes: v3: Replace S_IRWXUGO with 0777, per checkpatch v2: [dhowells] Merge the two xdr_encode_YFSStoreStatus*() functions together Signed-off-by: Marc Dionne <marc.dionne@auristor.com> Signed-off-by: David Howells <dhowells@redhat.com> Link: http://lists.infradead.org/pipermail/linux-afs/2021-October/004395.html
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
