[PATCH 2/8] vfs: export filp_clone_open()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Already exported to modules, just needs to move declaration from
"fs/internal.h" to <linux/fs.h>.

This will be used by overlayfs to clone a read-only file that has been
copied up after being opened.  The clone will refer to the copied-up uppper
file instead of the original, lower file.
