Hi. I've noticed that on file deletion from UFS with TRIM enabled, kernel issues BIO_DELETE for each 16K (block size?) separately -- thousands per second for single big file deletion. Fortunately ada driver will try to aggregate them for the device, but won't some clustering code worth to be there? -- Alexander Motin
