2023-04-06zonefs: Fix error message in zonefs_file_dio_append()Damien Le Moal
[ Upstream commit 88b170088ad2c3e27086fe35769aa49f8a512564 ] Since the expected write location in a sequential file is always at the end of the file (append write), when an invalid write append location is detected in zonefs_file_dio_append(), print the invalid written location instead of the expected write location.

2023-04-06zonefs: Separate zone information from inode informationDamien Le Moal
[ Upstream commit aa7f243f32e1d18036ee00d71d3ccfad70ae2121 ] In preparation for adding dynamic inode allocation, separate an inode zone information from the zonefs inode structure. The new data structure zonefs_zone is introduced to store in memory information about a zone that must be kept throughout the lifetime of the device mount. Linking between a zone file inode and its zone information is done by setting the inode i_private field to point to a struct zonefs_zone. Using the i_private pointer avoids the need for adding a pointer in struct zonefs_inode_info. Beside the vfs inode, this structure is reduced to a mutex and a write open counter. One struct zonefs_zone is created per file inode on mount. These structures are organized in an array using the new struct zonefs_zone_group data structure to represent zone groups. The zonefs_zone arrays are indexed per file number (the index of a struct zonefs_zone in its array directly gives the file number/name for that zone file inode).

2023-04-06zonefs: Reduce struct zonefs_inode_info sizeDamien Le Moal
[ Upstream commit 34422914dc00b291d1c47dbdabe93b154c2f2b25 ] Instead of using the i_ztype field in struct zonefs_inode_info to indicate the zone type of an inode, introduce the new inode flag ZONEFS_ZONE_CNV to be set in the i_flags field of struct zonefs_inode_info to identify conventional zones. If this flag is not set, the zone of an inode is considered to be a sequential zone. The helpers zonefs_zone_is_cnv(), zonefs_zone_is_seq(), zonefs_inode_is_cnv() and zonefs_inode_is_seq() are introduced to simplify testing the zone type of a struct zonefs_inode_info and of a struct inode.

[ Upstream commit 4008e2a0b01aba982356fd15b128a47bf11bd9c7 ] Move all code related to zone file operations from super.c to the new file.c file. Inode and zone management code remains in super.c.
