  f2fs: add a condition to detect overflow in f2fs_ioc_gc_range() (2019-09-17 13:56:15 -0700)

----------------------------------------------------------------
f2fs-for-5.4-rc1

In this round, we introduced casefolding support in f2fs, and fixed various bugs
in individual features such as IO alignment, checkpoint=disable, quota, and
swapfile.

Enhancement:
 - support casefolding w/ enhancement in ext4
 - support fiemap for directory
 - support FS_IO_GET|SET_FSLABEL

Bug fix:
 - fix IO stuck during checkpoint=disable
 - avoid infinite GC loop
 - fix panic/overflow related to IO alignment feature
 - fix livelock in swap file
 - fix discard command leak
 - disallow dio for atomic_write
