https://bugzilla.kernel.org/show_bug.cgi?id=105121 --- Comment #3 from Theodore Tso <tytso@xxxxxxx> --- This implies that grep is using lseek(SEEK_DATA) as an optimization when users use grep on sparse files. So I'm guessing this is a Thing, but I'm at a loss why people are interested in running grep on a sparse file (with or without blocks preallocated using fallocate). Can you enlighten me as to why people (or at least you and your colleague) find it useful to run grep on such files? Not that it matters since this is a pretty clear optimization we should add to ext4; I'm just curious what the use case is.
