Hi， all
When using the system call fallocate to pre-allocate more space on the tmpfs file
system, if the kernel returns an error EINTR, the original data on the file will
be lost (it seems to be the beginning of the file every time, the size is one page).
- Test case: https://github.com/abner-chenc/abner/blob/master/fallocate.c
- Kernel commit: b229b6ca5abbd63ff40c1396095b1b36b18139c3
- Arch: x86, loongarch64
