2.6.18 has comparable sys_close and filp_close, but the new filp_close does an
fflush() on the file. fflush(3) indicates that this is where all the previous
write() errors are picked up. The error-reference text used for the following
should be consistent:
close
fts
exec
fflush
fopen
hash
recno
dbopen
fclose
fseek
mpool
rpmatch
Yesterday I couldn't find the exact phrase.
