Subject: [PATCH v3 0/5] block: remove gfp_mask for blkdev_zone_mgmt()
Date: Sun, 28 Jan 2024 23:52:15 -0800 [thread overview]
Message-ID: <20240128-zonefs_nofs-v3-0-ae3b7c8def61@wdc.com> (raw)
Fueled by the LSFMM discussion on removing GFP_NOFS initiated by Willy,
I've looked into the sole GFP_NOFS allocation in zonefs. As it turned out,
it is only done for zone management commands and can be removed.
After digging into more callers of blkdev_zone_mgmt() I came to the
conclusion that the gfp_mask parameter can be removed alltogether.
So this series switches all callers of blkdev_zone_mgmt() to either use
GFP_KERNEL where possible or grab a memalloc_no{fs,io} context.
The final patch in this series is getting rid of the gfp_mask parameter.
