If not, it will fail with EINVAL. If no FIDTRIM is defined, it does not affect the "fstrim dotrim". Change-Id: Icbfd621abb592b170db06f749e5eedfd1175f723	10 years ago
Ken Sumrall	b87937cdea	Vold: Add the fstrim subsystem to vold The fstrim subsystem implements the dotrim command, which goes through all the writable filesystems on the device, and invokes the FITRIM ioctl() on them. This marks all the unused blocks on the underlying flash device as unused, so the device performs better. Change-Id: I5fc8c2f60e0bc823f162d0f89580fb288ecb2160	11 years ago

fstrim: prep for supporting a deep trim ioctl

This adds an "fstrim dodtrim" command which will attempt to use
the FIDTRIM ioctl() if FIDTRIM is defined in the uapi/linux/fs.h.
If not, it will fail with EINVAL.

If no FIDTRIM is defined, it does not affect the "fstrim dotrim".

Vold: Add the fstrim subsystem to vold

The fstrim subsystem implements the dotrim command, which goes
through all the writable filesystems on the device, and invokes
the FITRIM ioctl() on them.  This marks all the unused blocks on
the underlying flash device as unused, so the device performs better.
