5fede41205 Always use fallocate() on Linux for SHM creation 2023-09-23 10:55:15 +05:30

2e4f3dab41 Use fallocate() rather than truncate() when creating SHM memory
With truncate() the OS might not actually allocate the space leading to
a SIGBUS if /dev/shm runs out of space when actually using the mmap.

By using fallocate we ensure that once the SHM mmap is created it wont
fail
