Modified files:
lib/libstand close.c lseek.c open.c read.c stand.h
Log:
Implement readahead buffering for non-raw files. This drastically improves
the efficiency of byte-by-byte read operations on filesystems not already
supported by the block cache (especially NFS).
This should be a welcome change for users booting via PXE, as the loader
now reads its startup files almost instantly, instead of taking tens of
seconds.
