Thus, to completely free all clusters in a runlist, use * @start_vcn = 0 and @count = -1. * * If @ctx is specified, it is an active search context of @ni and its base mft * record. This is needed when ntfs_cluster_free() encounters unmapped runlist * fragments and allows their mapping. If you do not have the mft record * mapped, you can specify @ctx as NULL and ntfs_cluster_free() will perform * the necessary mapping and unmapping. * * Note, ntfs_cluster_free() saves the state of @ctx on entry and restores it * before returning. Thus, @ctx will be left pointing to the same attribute on * return as on entry. However, the actual pointers in @ctx may point to * different memory locations on return, so you must remember to reset any * cached pointers from the @ctx, i.e. after the call to ntfs_cluster_free(), * you will probably want to do: * m = ctx->mrec; * a = ctx->attr; * Assuming you cache ctx->attr in a variable @a of type ATTR_RECORD * and that * you cache ctx->mrec in a variable @m of type MFT_RECORD *. * * Note, ntfs_cluster_free() does not modify the runlist, so you have to remove * from the runlist or mark sparse the freed runs later. * * Return the number of deallocated clusters (not counting sparse ones) on * success and -errno on error. * * WARNING: If @ctx is supplied, regardless of whether success or failure is * returned, you need to check IS_ERR(@ctx->mrec) and if 'true' the @ctx * is no longer valid, i.e. you need to either call * ntfs_attr_reinit_search_ctx() or ntfs_attr_put_search_ctx() on it. * In that case PTR_ERR(@ctx->mrec) will give you the error code for * why the mapping of the old inode failed. * * Locking: - The runlist described by @ni must be locked for writing on entry * and is locked on return. Note the runlist may be modified when * needed runlist fragments need to be mapped. * - The volume lcn bitmap must be unlocked on entry and is unlocked * on return. * - This function takes the volume lcn bitmap lock for writing and * modifies the bitmap contents. * - If @ctx is NULL, the base mft record of @ni must not be mapped on * entry and it will be left unmapped on return. * - If @ctx is not NULL, the base mft record must be mapped on entry * and it will be left mapped on return. */ static inline s64 ntfs_cluster_free(ntfs_inode *ni, const VCN start_vcn, s64 count, ntfs_attr_search_ctx *ctx) { return __ntfs_cluster_free(ni, start_vcn, count, ctx, false); } extern int ntfs_cluster_free_from_rl_nolock(ntfs_volume *vol, const runlist_element *rl); /** * ntfs_cluster_free_from_rl - free clusters from runlist * @vol: mounted ntfs volume on which to free the clusters * @rl: runlist describing the clusters to free * * Free all the clusters described by the runlist @rl on the volume @vol.

ARM: dts: orion5x-lschl: Fix model name
Model name should be consistent with legacy device file, so that user can migrate their system from legacy device support to device-tree safely. Legacy device file is currently removed, but it can be found on 4.8 or previous version of linux: arch/arm/mach-orion5x/ls-chl-setup.c Fixes: f94f268979a2 ("ARM: dts: orion5x: convert ls-chl to FDT") Cc: Ashley Hughes <ashley.hughes@blueyonder.co.uk> Signed-off-by: Roger Shimizu <rogershimizu@gmail.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
