Jan Kara f871cd8ee0 ext4: avoid trim error on fs with small groups ... [ Upstream commit 173b6e383d2a204c9921ffc1eca3b87aa2106c33 ] A user reported FITRIM ioctl failing for him on ext4 on some devices without apparent reason. After some debugging we've found out that these devices (being LVM volumes) report rather large discard granularity of 42MB and the filesystem had 1k blocksize and thus group size of 8MB. Because ext4 FITRIM implementation puts discard granularity into minlen, ext4_trim_fs() declared the trim request as invalid. However just silently doing nothing seems to be a more appropriate reaction to such combination of parameters since user did not specify anything wrong.
