6697ffd6e2 fusefronted: reject GETXATTR "security.capability" 
Unless we are mounted with -suid, we can reject
these requests, and gain back some lost speed.

ec3eaf0b87 syscallcompat: don't retry Close() 
After Close() returns, the fd is dead, even if we
received EINTR. Don't retry, we could shoot down
an unrelated fd that received the same fd number.

af4c1fb7a3 syscallcompat: retry ops on EINTR 
Retry operations that have been shown to throw EINTR
errors on CIFS.

Todo: Solution for this pain in the back:

	warning: unix.Getdents returned errno 2 in the middle of data
	rm: cannot remove 'linux-3.0.old3/Documentation/ABI/removed': Input/output error

Progress towards fixing https://github.com/rfjakob/gocryptfs/issues/483 .

fe340477b2 build.bash: show "go mod edit -replace" in version string 
If you do something like this,

  go mod edit -replace github.com/hanwen/go-fuse/v2=/home/jakob/go/src/github.com/hanwen/go-fuse

the version string of the resulting binary should reflect that.

Before:

  gocryptfs v1.8.0-135-g352b547-dirty.gofuse_v2api; go-fuse v2.0.4-0.20200908172753-0b6cbc515082; 2020-10-03 go1.15.2 linux/amd64

After:

  gocryptfs v1.8.0-135-g352b547-dirty.gofuse_v2api; go-fuse v2.0.4-0.20200908172753-0b6cbc515082 => /home/jakob/go/src/github.com/hanwen/go-fuse; 2020-10-03 go1.15.2 linux/amd64

3c5a80c27b fsstress-gocryptfs.bash: don't hang if TMPDIR ends in / 
We would hang like this

   ./fsstress-loopback.bash
  Recompile go-fuse loopback: v2.0.3-7-g0b6cbc5
  Waiting for mount: xxxxxxxx^C

if TMPDIR has a trailing /. The reason is that the
paths in /proc/self/mounts are normalized, while
TMPDIR may not be.

af7386713c stress_tests/fsstress-gocryptfs.bash: use rm -Rf for cleanup 
Apparently, kernel 5.8 now allows unprivileged "mknod /tmp/x c 0 0":

	vfs: allow unprivileged whiteout creation
	https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.8.9&id=a3c751a50fe6bbe50eb7622a14b18b361804ee0c

which is why rm throws a new prompt:

	rm: remove write-protected character special file '...'?

Use rm -Rf to suppress that.
