| Subject | [PATCH 2/3] f2fs: fix to wait all atomic written pages writeback |
| Message-ID | <pNaKC-2i1-17@gated-at.bofh.it> |
This patch fixes the incorrect range (0, LONG_MAX) which is used in ranged fsync. If we use LONG_MAX as the parameter for indicating the end of file we want to synchronize, in 32-bits architecture machine, these datas after 4GB offset may not be persisted in storage after ->fsync returned. Here, we alter LONG_MAX to LLONG_MAX to fix this issue.
