Subject: [PATCH 6/6] Backport: vfs: make O_PATH file descriptors usable for
|
||
|
|
'fstat()'

We already use them for openat() and friends, but fstat() also wants to
|
||
|
|
be able to use O_PATH file descriptors. This should make it more
|
||
|
|
directly comparable to the O_SEARCH of Solaris.
|
||
|
|
|
||
|
|
Note that you could already do the same thing with "fstatat()" and an
|
||
|
|
empty path, but just doing "fstat()" directly is simpler and faster, so
|
||
|
|
there is no reason not to just allow it directly.
|
||
|
|
|
||
|
|
See also commit 332a2e1, which did the same thing for fchdir, for
|
||
|
|
the same reasons.
