[LTP] [PATCH 0/5] Add LVM and NFS tests for file data integrity

[Martin Doucha]

Most of the existing read/write tests don't verify whether the data written
to the filesystem can also be correctly read back. Add a new reusable test
program that will check file data integrity. The test randomly switches
between multiple read/write syscalls and allows setting direct (unbuffered)
I/O mode independently for read or write operations.

Also enable the new test in LVM and NFS runfiles with all combinations
of direct and buffered I/O operations.

Martin Doucha (5):
  Move preadv()/pwritev() backup definitions to LAPI
  Add safe readv()/writev() functions
  Add test for file data integrity
  Add support for setting loop device size in shell tests
  Add test for data integrity over NFS
