Subject: [PATCH 0/6] Make block_read_full_page synchronous
Date: Thu, 22 Oct 2020 22:22:22 +0100 [thread overview]
Message-ID: <20201022212228.15703-1-willy@infradead.org> (raw)
This patchset does I/Os in larger chunks, if the blocks are adjacent.
More importantly, it returns the actual error from ->readpage for
filesystems which use block_read_full_page(). Unless fscrypt returns
an error, in which case it turns into EIO because it has to roundtrip
through bi_status.
I don't have a system with fscrypt enabled, so I'd appreciate some
testing from the fscrypt people.
Matthew Wilcox (Oracle) (6):
block: Add blk_completion
fs: Return error from block_read_full_page
fs: Convert block_read_full_page to be synchronous
fs: Hoist fscrypt decryption to bio completion handler
fs: Turn decrypt_bh into decrypt_bio
fs: Convert block_read_full_page to be synchronous with fscrypt
enabled
