ext4: use filemap_write_and_wait_range() correctly in collapse range
Currently we're passing -1 as lend argumnet for filemap_write_and_wait_range() which is wrong since lend is signed type so it would cause some confusion and we might not write_and_wait for the entire range we're expecting to write. Fix it by using LLONG_MAX instead. Signed-off-by: Lukas Czerner <lczerner@redhat.com> Signed-off-by: "Theodore Ts'o" <tytso@mit.edu>
