Subject: ext4: add FITRIM to compat_ioctl.
X-Git-Tag: firefly_0821_release~7613^2~1801^2~6
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=a56e69c28ad0782a99f3f196e93d57ba5a7e2324;p=firefly-linux-kernel-4.4.55.git

ext4: add FITRIM to compat_ioctl.

FITRIM isn't added in compat_ioctl. So a 32 bit program can't be executed
in a 64 bit platform. Add it in the compat_ioctl.
