[f2fs-dev] 答复: [PATCH] f2fs: prevent newly created inode from being dirtied incorrectly

Hi Daeho: We had tried to msleep(1) after f2fs_mark_inode_dirty_sync() in creating a new file, and then write checkpoint in another thread. But it didn't cause a kernel panic. So can you tell me what test case did you use, and provide the call trace? Thank you! Best regards, Zhikang Zhang

Re: [f2fs-dev] [PATCH v2 00/11] fscrypt: symlink helpers and fscrypt.h cleanup

I've taken the v2 version of this series, plus the ext4-specific patches to use the new symlink helpers (from the v1 patch series). After testing and validating them, I included the patches to convert f2fs and ubifs to use the symlink helpers, so I could also grab the cleanup patches from the V1

[f2fs-dev] [PATCH] f2fs: prevent newly created inode from being dirtied incorrectly

Now, we invoke f2fs_mark_inode_dirty_sync() to make an inode dirty in advance of creating a new node page for the inode. By this, some inodes whose node page is not created yet can be linked into the global dirty list. If the checkpoint is executed at this moment, the inode will be written back
